Are there different colors to henna?
Henna
Henna stains are orange when the paste is first removed, but darken over the following three days to a deep reddish brown due to oxidation. Soles and palms have the thickest layer of skin and so take up the most lawsone, and take it to the greatest depth, so that hands and feet will have the darkest and most long-lasting stains. Some also believe that steaming or warming the henna pattern will darken the stain, either during the time the paste is still on the skin, or after the paste has been removed. It is debatable whether this adds to the color of the end result as well. After the stain reaches its peak color, it holds for a few days, then gradually wears off by way of exfoliation, typically within 1 to 3 weeks. Adding drops of lemon juice to your new hand of henna will make it last longer.
Sienna (given name)
Sienna is a feminine given name currently popular in Great Britain, New Zealand and Australia, where it was among the top ten names given to baby girls in 2006 and 2007 in several states. The original usage of the name is derived from the Italian city and may also refer to the orange-red color of its clay rooftops burnt orange. The eye color, human skin color, and human hair color of mulattos are all called raw sienna, but never burnt sienna, and the colors of Virginia Tech are burnt orange and maroon, not sienna.
Blue hair
In some works by Homer, characters are said to have dark blue ("kyaneos") hair or eyebrows when they are angry or in an emotionally intense state. For example, Odysseus' beard became black blue when he was transformed by Athena upon returning home to confront his wife's suitors. Other Greek gods were also shown as having blue hair. This imagery may stem from Egyptian myth, in which their gods were said to have hair of lapis lazuli. In a similar vein, characters from the Bible, such as Eve, Leah, and Rachel, are often depicted with a "sky-blue" color of hair.
Color in ancient Greece and Egypt were also more expressive rather than natural: blue or gold indicated divinity because of its unnatural appearance and association with precious materials.
Henna
Apart from Henna being used for dying on hair, it has been recently used as a temporal substitute to eyebrow pencil or even eyebrow embroidery. Eyebrow henna is a quick and effective replacement to daily application of eyebrow makeup which helps save time for anyone that wants a well-defined eyebrow.
Bengal cat
"Jean Mill was originally from Des Moines Iowa. Mill moved to California to attend Pomona College where she earned a degree in psychology. Mill then took several graduate classes in genetics at UC Davis. By 1948, Mill was one of three breeders working to develop the Himalayan cat, "a longhaired breed of mixed Persian and Siamese ancestry)."
By the 2000's Bengals have become a very popular breed. The Bengal breed was more fully developed by the 1980s. "In 1992 The International Cat Association had 125 registered Bengal Breeders." In 2019 there are more than 1000 Bengal breeders worldwide.
People most often associate the Bengal with the most popular color: the Brown spotted/rosetted Bengal. However, Bengals have a wide variety of markings and colors. Even within the Brown spotted/rosetted category a Bengal can be: red, brown, black, ticked, grey, spotted, rosetted, clouded. Many people are stunned by the Bengal Cat's resemblance to a leopard. Among domestic cats, the Bengal markings are perhaps the most varied and unique.
Siamese fighting fish
Bettas are found in many different colours due to different layers of pigmentation in their skin. The layers (from furthest within to the outer layer) consists of red, yellow, black, iridescent (blue and green), and metallic (not a colour of its own, but reacts with the other colours to change how they are perceived). Any combination of these layers can be present, leading to a wide variety of colours.
The shades of blue, turquoise, and green are slightly iridescent, and can appear to change colour with different lighting conditions or viewing angles; this is because these colours (unlike black or red) are not due to pigments, but created through refraction within a layer of translucent guanine crystals. Breeders have also developed different colour patterns such as marble and butterfly, as well as metallic shades through hybridization like copper, gold, or platinum (these were obtained by crossing "B. splendens" to other "Betta" species).
A true albino betta has been feverishly sought since one recorded appearance in 1927, and another in 1953. Neither of these was able to establish a line of true albinos. In 1994, a hobbyist named Kenjiro Tanaka claimed to have successfully bred albino bettas.
Hair coloring
Diodorus Siculus, a Greek historian, described in detail how Celtic people dyed their hair blonde:
"Their aspect is terrifying... They are very tall in stature, with rippling muscles under clear white skin. Their hair is blond, but not naturally so: they bleach it, to this day, artificially, washing it in lime and combing it back from their foreheads. They look like wood-demons, their hair thick and shaggy like a horse's mane. Some of them are clean-shaven, but others—especially those of high rank—shave their cheeks but leave a moustache that covers the whole mouth...".
This practice continued in some parts of Britain long after the Fall of the Western Roman Empire, particularly in Wales, where Llywelyn Ap Gruffudd was described in an elegy by Gruffudd ab yr Ynad Coch to have blonde hair: "...Not since Camlann has there been such weeping, Gone is our mainstay, his golden hair, stained with a death blow...".
The dyeing of hair is an ancient art that involves treatment of the hair with various chemical compounds. In ancient times, the dyes were obtained from plants. Some of the most well known are henna ("Lawsonia inermis"), indigo, "Cassia obovata", senna, turmeric and amla. Others include katam ("buxus dioica"), black walnut hulls, red ochre and leeks. In the 1661 book "Eighteen Books of the Secrets of Art & Nature", various methods of coloring hair black, gold, green, red, yellow, and white are explained. The development of synthetic dyes for hair is traced to the 1860s discovery of the reactivity of para-phenylenediamine (PPD) with air. Eugène Schueller, the founder of L'Oréal, is recognized for creating the first synthetic hair dye in 1907. In 1947 the German cosmetics firm Schwarzkopf launched the first home color product, "Poly Color". Hair dyeing is now a multibillion-dollar industry that involves the use of both plant-derived and synthetic dyes.
Potassium bitartrate
For dyeing hair, potassium bitartrate can be mixed with henna as the mild acid needed to activate the henna.
Red
Red hair varies from a deep burgundy through burnt orange to bright copper. It is characterized by high levels of the reddish pigment pheomelanin (which also accounts for the red color of the lips) and relatively low levels of the dark pigment eumelanin. The term redhead (originally "redd hede") has been in use since at least 1510. Cultural reactions have varied from ridicule to admiration; many common stereotypes exist regarding redheads and they are often portrayed as fiery-tempered. (See red hair).
Red banana
Red bananas are a group of varieties of banana with reddish-purple skin. Some are smaller and plumper than the common Cavendish banana, others much larger. When ripe, raw red bananas have a flesh that is cream to light pink in color. They are also softer and sweeter than the yellow Cavendish varieties, some with a slight raspberry flavor and others with an earthy one. Many red bananas are exported by producers in East Africa, Asia, South America and the United Arab Emirates. They are a favorite in Central America but are sold throughout the world.
Sienna
Sienna (from , "Siena earth") is an earth pigment containing iron oxide and manganese oxide. In its natural state, it is yellow-brown and is called raw sienna. When heated, it becomes a reddish brown and is called burnt sienna. It takes its name from the city-state of Siena, where it was produced during the Renaissance. Along with ochre and umber, it was one of the first pigments to be used by humans, and is found in many cave paintings. Since the Renaissance, it has been one of the brown pigments most widely used by artists.
Impatiens
Certain jewelweeds, including the garden jewelweed contain the naphthoquinone lawsone, a dye that is also found in henna ("Lawsonia inermis") and is also the hair coloring and skin coloring agent in mehndi. In ancient China, "Impatiens" petals mashed with rose and orchid petals and alum were used as nail polish: leaving the mixture on the nails for some hours colored them pink or reddish.
Chestnut (coat)
Chestnuts can vary widely in shade and different terms are sometimes used to describe these shades, even though they are genetically indistinguishable. Collectively, these coat colors are usually called "red" by geneticists.Chestnut is considered a "base color" in the discussion of equine coat color genetics. Additional coat colors based on chestnut are often described in terms of their relationship to chestnut:Combinations of multiple dilution genes do not always have consistent names. For example, "dunalinos" are chestnuts with both the dun gene and one copy of the cream gene.The chestnut color, called "red" by geneticists, is created by an allele that is a mutation from the wildtype and is genetically the most recessive coat color that exists in modern horses. The gene for "red" color is designated as "e". This is because the presence or absence of red color in horses is determined by the equine melanocortin-1-receptor (MC1R), a protein positioned on chromosome 3 (ECA3) at the Extension locus. The wild type version of the gene encoding MC1R is the "E" allele (colloquially, though imprecisely, called the "Extension gene"), and is part of the genetic pathway that allows melanocytes to produce eumelanin, or black pigment. When the "E" allele is not present, no eumelanin is produced, but the "e" allele still allows melanin to be produced in the form of pheomelanin, or red pigment, creating a chestnut or red-based coat color. In general, alleles that create fully functional MC1R proteins are inherited dominantly and result in a black-based coat color ("E"), while mutated alleles that create "dysfunctional" MC1R are recessive and result in a lighter coat color ("e").
Historic paint analysis
The hue notation, the color, indicates the relation of the sample to a visually equally spaced scale of 100 hues. There are 10 major hues, five principal and five intermediate within this scale. The hues are identified by initials indicating the central member of the group: red R, yellow-red YR, yellow Y, yellow-green YG, green G, blue-green BG, blue B, purple-blue PB, purple P, and red-purple PR. The hues in each group are identified by the numbers 1 to 10. The most purplish of the red hues, 1 on the scale of 100, is designated as 1R, the most yellowish as 10R, and the central hue as 5R. The hue 10R can also be expressed as 10, 5Y as 25, and so forth if a notation of the hue as a number is desired. Chroma indicates the degree of departure of a given hue from the neutral gray axis of the same value. It is the strength of saturation of color from neutral gray, written /0 to /14 or further for maximum color saturation.
Tenné
In heraldry, tenné (; sometimes termed tenny or tawny) is a "stain", or non-standard tincture, of orange (in English blazonry), light brown (in French heraldry) or orange-tawny (in continental heraldry) colour.
Tincture (heraldry)
Tenné or tenny, from Latin "tannare", "to tan", is the second of the so-called "stains". It is most often depicted as orange, but sometimes as tawny yellow or brown. In earlier times it was occasionally used in continental heraldry, but in England largely confined to livery.
Body painting
Body painting with a grey or white paint made from natural pigments including clay, chalk, ash and cattle dung is traditional in many tribal cultures. Often worn during cultural ceremonies, it is believed to assist with the moderation of body heat and the use of striped patterns may reduce the incidence of biting insects. It still survives in this ancient form among Indigenous Australians and in parts of Africa and Southeast Asia, as well as in New Zealand and the Pacific islands. A semi-permanent form of body painting known as "Mehndi", using dyes made of henna leaves (hence also known rather erroneously as "henna tattoo"), is practiced in India, especially on brides. Since the late 1990s, Mehndi has become popular amongst young women in the Western world.
Henry S. Lane House
The house has been painted various colors since 1845. The Lane Place was painted white through all the additions to the house while Henry and Joanna lived at the property. After Henry's death on June 18, 1881, Joanna painted the house gray in mourning. The house was temporarily painted pink under Helen's ownership from around 1914 to 1920. In 1920 the house was painted yellow. The house remained yellow until 1945 when The Montgomery County Historical Society decided to return it to white. The house has remained white since then.
Himba people
Several researchers have studied the OvaHimba perception of colours. The OvaHimba use four colour names: "zuzu" stands for dark shades of blue, red, green and purple; "vapa" is white and some shades of yellow; "buru" is some shades of green and blue; and "dambu" is some other shades of green, red and brown. It is thought that this may increase the time it takes for the OvaHimba to distinguish between two colours that fall under the same Herero colour category, compared to people whose language separates the colours into two different colour categories.
Umber
Umber is not one precise color, but a range of different colors, from medium to dark, from yellowish to reddish to grayish. The color of the natural earth depends upon the amount of iron oxide and manganese in the clay. Umber earth pigments contain between five and twenty percent manganese oxide, which accounts for their being a darker color than yellow ochre or sienna.
Commercial colors vary depending upon the manufacturer or the color list. Not all umber pigments contain natural earths; some contain synthetic iron and manganese oxide, indicated on the label. Pigments containing the natural umber earths indicate them on the label as PBr7 (Pigment brown 7), following the Colour Index International system.
Tenné
Perhaps as a symptom of the theoretical nature of heraldic stains, the hatchings assigned to these have been inconsistent among sources. The hatching for tenné has been given variously as a combination of vertical lines (as gules) and dexter to sinister lines (as vert), or as a combination of horizontal lines (as azure) and sinister to dexter lines (as purpure), (and other combinations may be found in other sources) though both these sources provide the same hatching of alternating vertical dots and dashes for "orange".
Assyrian culture
Henna is mud-like material that is prepared on the day before the wedding. On night for the wedding, in the old days all the ladies would gather at the house of the bride (but nowadays it's mixed, also male relatives and family friends are invited.) A bowl is filled with henna. Henna is celebrated differently throughout the Assyrian community.
In some areas, whoever holds the bowl with the henna will dance with it around the others. 
The groom and bride put in the bowl their little finger and their little finger will be wrapped and connected to each other by a ribbon.
In other areas, everyone is given a turn to wrap his finger with henna, and after everyone, the person that is getting henna in his hand starts the chant of praise for the future couple, as everyone else follows him.
Senna italica
Reports on the uses of "Senna italica" is contradictory. In East Africa, it is eaten by most livestock, whereas in West Africa, it is often avoided. In Sahel regions, young seeds are eaten as snacks or a vegetable. On the other hand, the seeds are smoked in Mauritania. In India, the leaves are used as a hair treatment called neutral henna or “blonde henna”. This treatment coats the hair so that it looks glossy and thick for several weeks, but instead of being completely neutral, "neutral henna" appears to have a yellowish impact on hair rather than the reddish one produced by henna. Fruit production of this plant is generally avoided, as their sennoside content is low.
Tenné
According to the "Oxford Guide to Heraldry", a late-14th century English treatise on heraldry stated that a colour called "tawny" was "borne only in the Empire and France." Fox-Davies suggested that orange, as it appears in German heraldry, may be a different colour than tenné, noting that a different hatching is associated with German "orange" than that of British "tenné". German heraldic author Ottfried Neubecker also noted a distinction between "orange" and "brown" or "tenné", showing the usual hatching for tenné but a distinctive hatching of alternating vertical dots and dashes for orange. Orangé, tanné and tenné appear in the civic arms of several communes in the Department of Oise in France.
Henna
It is not difficult to recognize and avoid PPD black henna:
Henna
PPD black henna use is widespread, particularly in tourist areas. Because the blistering reaction appears 3 to 12 days after the application, most tourists have left and do not return to show how much damage the artist has done. This permits the artists to continue injuring others, unaware they are causing severe injuries. The high-profit margins of black henna and the demand for body art that emulates "tribal tattoos" further encourage artists to deny the dangers.
Yemenite Jews
Before the wedding, Yemenite and other Eastern Jewish communities perform the henna ceremony, an ancient ritual with Bronze Age origins. The family of the bride mixes a paste derived from the henna plant that is placed on the palms of the bride and groom, and their guests. After the paste is washed off, a deep orange stain remains that gradually fades over the next week.
Persian cat
The Cat Fanciers' Association (CFA), of the United States, groups the breed into four coat-pattern divisions, but differently: solid, silver and golden (including chinchilla and shaded variants, and blued subvariants), shaded and smoke (with several variations of each, and a third sub-categorization called shell), tabby (only classic, mackerel, and patched [spotted], in various colors), parti-color (in four classes, tortoiseshell, blue-cream, chocolate tortie, and lilac-cream, mixed with other colors), calico and bi-color (in around 40 variations, broadly classified as calico, dilute calico, and bi-color), and Himalayan (white-to-fawn body with point coloration on the head, tail and limbs, in various tints). CFA base colors are white, black, blue, red, cream, chocolate, and lilac. There are around 140 named CFA coat patterns for which the Himalayan qualifies, and 20 for the Himalayan sub breed. These coat patterns encompass virtually all of those recognized by CFA for cats generally. Any Persian permissible in TICA's more detailed system would probably be accepted in CFA's, simply with a more general name, though the organizations do not mix breed registries.
Hair highlighting
Hair highlighting/lowlighting is changing a person's hair color, using lightener or haircolor to color hair strands. There are four basic types of highlights: foil highlights, hair painting, frosting, and chunking. Highlights can be done in natural or unnatural colors. Color highlights come in four categories: temporary, semi-permanent, demi-permanent and permanent. Hair lightened with bleach or permanent color will be permanent until new growth begins to growth. Highlighted hair will make the hair appear fuller. Therefore, it is recommended on people with thin and fine hair. It also recommended for people with at least 50 % gray for easy blending and to diminish the line of demarcation once the new growth is showing.
Honey bee race
Differences in the colors of bees may be more pronounced in queens and drones; workers are much less easily differentiated by color. Drones are produced from the unfertilized eggs of queens and therefore their genetic characteristics depend entirely on those of the queen, whereas worker bees are produced from fertilized eggs. To make things even more complicated, a queen will normally mate multiple times, the spermatozoa from which are retained within her body meaning that workers may only be half-sisters to each other, and their colors and other characteristics may differ.
Havana rabbit
The Havana is a breed of rabbit that first appeared in the Netherlands in 1898. The breed is ancestral to several others, including the Fee de Marbourg, Perlefee and Gris Perle de Hal. Havanas are recognized by the American Rabbit Breeders Association in five color types: chocolate, lilac, black, blue, and broken. Their average weight is between and .
Henna
Powdered fresh henna, unlike premixed paste, can be easily shipped all over the world and stored for many years in a well-sealed package.
Hairstyles in the 1950s
Short, tight curls with a poodle cut known as "short bangs" were very popular, favored by women such as first lady Mamie Eisenhower. Henna was a popular hair dye in the 1950s in the US; in the popular TV comedy series "I Love Lucy", Lucille Ball (according to her husband’s statement) “used henna rinse to dye her brown hair red.” The poodle cut was also made popular by Audrey Hepburn. In the 1953 film "Roman Holiday", Audrey Hepburn's character had short hair known as a “gamine-style” pixie cut, which accentuated her long neck, and which was copied by many women. In the film "Sabrina", her character appears initially in long plain hair while attending culinary school, but returns to her Paris home with a chic, short, face-framing "Paris hairstyle", which again was copied by many women. When the rage among women was for the “blond bombshell” hair style, Hepburn stuck to her dark brown hair color and refused to dye her hair for any film.
Unique hues
There has been considerable effort in neuroscience to establish physiological mechanisms correlating to the existence of unique hues. For some time it was thought that the opponent process was explained through two chromatic mechanisms inherent in the way signals from the three cone types (Long, Medium, and Short wavelengths) on the retina are processed. The first mechanism represents the red-green L-M process. The blue-yellow process was thought to be based on a similar (L+M)-S process. Recent research has shown that this (L+M)-S process does correspond to yellow as a unique hue. This has led to the idea of unique hues being a result of higher order processing in the lateral geniculate nucleus (LGN).
Spotted hyena
Fur colour varies greatly and changes with age. Unlike the fur of the striped and brown hyena, that of the spotted hyena consists of spots rather than stripes and is much shorter, lacking the well defined spinal mane of the former two species. The base colour generally is a pale greyish-brown or yellowish-grey on which an irregular pattern of roundish spots is superimposed on the back and hind quarters. The spots, which are of variable distinction, may be reddish, deep brown or almost blackish. The spots vary in size, even on single individuals, but are commonly in diameter. A less distinct spot pattern is present on the legs and belly but not on the throat and chest. A set of five, pale and barely distinct bands replace the spots on the back and sides of the neck. A broad, medial band is present on the back of the neck, and is lengthened into a forward facing crest. The crest is mostly reddish-brown in colour. The crown and upper part of the face is brownish, save for a white band above both eyes, though the front of the eyes, the area around the rhinarium, the lips and the back portion of the chin are all blackish. The limbs are spotted, though the feet vary in colour, from light brown to blackish. The fur is relatively sparse and consists of two hair types; moderately fine underfur (measuring ) and long, stout bristle hairs (). European Paleolithic rock art depicting the species indicates that the Eurasian populations retained the spots of their modern-day African counterparts.
Yellow
In color printing, yellow is one of the three colors of ink, along with magenta and cyan, which, along with black, can be overlaid in the right combination, along with black, to print any full color image. (See the CMYK color model). A particular yellow is used, called Process yellow (also known as "pigment yellow", "printer's yellow", and "canary yellow") subtractive primary colors, along with magenta and cyan. Process yellow is not an RGB color, and there is no fixed conversion from CMYK primaries to RGB. Different formulations are used for printer's ink, so there can be variations in the printed color that is pure yellow ink.
Red hair
In Asia, genetic red hair is rare, but reddish-brown (auburn) hair can be found in the Levant (Syria, Lebanon, Jordan, Israel and Palestine), in Turkey, in Caucasia, in Northern Kazakhstan, and among Uyghurs. The use of henna on hair and skin for various reasons occasionally occurs in Asia. When henna is used on hair it dyes the hair to different shades of red.
Henna
Bridal henna nights are a popular tradition in North Africa, the Horn of Africa, South East Asia, the Arabian Peninsula, the Near East and the Indian subcontinent.
Hair coloring
Temporary hair color is available in various forms including rinses, shampoos, gels, sprays, and foams. Temporary hair color is typically brighter and more vibrant than semi-permanent and permanent hair color. It is most often used to color hair for special occasions such as costume parties and Halloween.
Peonidin
Like most anthocyanidins, it is pH sensitive, and changes from red to blue as pH rises because anthocyanidins are highly conjugated chromophores. When the pH is changed, the extent of the conjugation (of the double bonds) is altered, which alters the wavelength of light energy absorbed by the molecule. (Natural anthocyanidins are most stable in a very low pH environment; at pH 8.0, most become colorless.) At pH 2.0, peonidin is cherry red; at 3.0 a strong yellowish pink; at 5.0 it is grape red-purple; and at 8.0 it becomes deep blue; unlike many anthocyanidins, however, it is stable at higher pH, and has been isolated as a blue colorant from the brilliant "Heavenly Blue" morning glory ("Ipomoea tricolor Cav cv").
Magenta
Magenta () is a color that is variously defined as purplish-red, reddish-purple, purplish, or mauvish-crimson. In the RGB color model, it is made by mixing equal amounts of blue and red. On color wheels of the RGB (additive) and CMY (subtractive) color models, it is located midway between red and blue. It is the complementary color of green. It is one of the four colors of ink used in color printing by an inkjet printer, along with yellow, black, and cyan, to make all the other colors. The tone of magenta used in printing is called "printer's magenta".
Henna
In Europe, henna was popular among women connected to the aesthetic movement and the Pre-Raphaelite artists of England in the 1800s. Dante Gabriel Rossetti's wife and muse, Elizabeth Siddal, had naturally bright red hair. Contrary to the cultural tradition in Britain that considered red hair unattractive, the Pre-Raphaelites fetishized red hair. Siddal was portrayed by Rossetti in many paintings that emphasized her flowing red hair. The other Pre-Raphaelites, including Evelyn De Morgan and Frederick Sandys, academic classicists such as Frederic Leighton, and French painters such as Gaston Bussière and the Impressionists further popularized the association of henna-dyed hair and young bohemian women.
Swedish Flower Hen
The Blommehöna is characterised by its millefleur plumage pattern. The base colour is variable, and may be black, blue, buff or red.
Hadena confusa
The wingspan is 27–35 mm. The forewing ground colour is purplish fuscous tinged with olive grey. The stigmata are fused together forming a large white patch and there is a small white apical blotch. The subterminal line is white in colour and irregular wavy and joins the apical white stain.The basal field shows a more or less pronounced whitening.The fringe is chequered. The hindwings are fuscous with a small discal lunule and white fringe.The hindwings are slightly darker on the outside In very humid areas melanistic individuals can occur primarily on the Shetland and Orkney Islands, parts of the Hebrides, as well as in Wales and Scotland.
Henna
The fashion of "Bridal Mehndi" in North Indian, Bangladesh, Northern Libya and in Pakistan is currently growing in complexity and elaboration, with new innovations in glitter, gilding, and fine-line work. Recent technological innovations in grinding, sifting, temperature control, and packaging henna, as well as government encouragement for henna cultivation, have improved dye content and artistic potential for henna.
Mehndi
Alta, Alata, or Mahur is a red dye used similarly to henna to paint the feet of the brides in some regions of India, for instance in Bengal.
List of colors by shade
Magenta is variously defined as a purplish-red, reddish-purple, or a mauvish–crimson color. On color wheels of the RGB and CMY color models, it is located midway between red and blue, opposite green. Complements of magenta are evoked by light having a spectrum dominated by energy with a wavelength of roughly 500–530 nm. It is considered one of the subtractive primary colors.
Henna
Muslim men may use henna as a dye for hair and most particularly their beards. This is considered "sunnah", a commendable tradition of the Prophet Muhammad. Furthermore, a "hadith" (narration of the Prophet) holds that he encouraged Muslim women to dye their nails with henna to demonstrate femininity and distinguish their hands from those of men. Thus, some Muslim women in the Middle East apply henna to their finger and toenails as well as their hands.
Honda Ridgeline
The Gen1 Ridgeline was offered in three to seven different exterior colors as well as one to three interior colors, depending on country, model year, and trim level. Exterior colors were based on different shades of black, gray, white, silver, blue, and red as well as some short-lived green and brown colors. All of the exterior colors were monotone with some black and/or chrome plastic trim. Most interior colors ranged between olive, beige, gray, and black. These interior colors were found in the cloth or leather upholstery as well as some of the interior panel covers. Additionally, these interior colors were mated to specific exterior colors and trim levels leaving buyers no means to mix and match interior and exterior color options.
In addition to the different features and accessories one could obtain by purchasing certain trim levels, Honda also offered many of them as Original Equipment Manufacturer (OEM) accessories that could be ordered and installed at the dealership. Additionally, there were numerous Honda accessories that did not come on any trim level which could be purchased and installed at the dealership including:
Human hair color
Hair color is the pigmentation of hair follicles due to two types of melanin: eumelanin and pheomelanin. Generally, if more eumelanin is present, the color of the hair is darker; if less eumelanin is present, the hair is lighter. Levels of melanin can vary over time causing a person's hair color to change, and it is possible to have hair follicles of more than one color on the same person. Particular hair colors are often associated with ethnic groups, while gray or white hair is associated with age.
Tertiary color
The terms for the RYB tertiary colors are not set. For the six RYB hues intermediate between the RYB primary and secondary colors, the names amber/marigold (yellow–orange), vermilion/cinnabar (red–orange), magenta (red–purple), violet (blue–purple), teal/aqua (blue-green), and chartreuse/lime green (yellow–green) are commonly found. The names for the twelve quaternary colors are more variable, if they exist at all, though indigo and scarlet are standard for blue–violet and red–vermilion.
Coton de Tulear
The Coton de Tulear comes in three accepted colors: white (sometimes with tan markings; all white is preferred by show breeders); black and white; and tricolor. However, the tan and white may become all white, the blacks will often fade to grey or white, and fur will most likely change throughout puppyhood. The breed even has a fade gene that causes the colors, which are very dark when a puppy, to fade and turn white at the base of the hair as it lengthens; that is why the Champagne or Champagne Teddy Bear Coton eventually turns white when the adult hair comes in.) The Fédération Cynologique Internationale standard specifies that the Coton's coat should be white, but may also have tan or "lemon" color on their ears and body. The coat, however, must be primarily white with no black hair. The US-based Coton de Tulear Club of America allows for three different but equally favorable colorings: white, black-and-white, and tri-color, which includes "honey bear". White is described as nearly all white, sometimes with tan or champagne coloring on the ears, face or back. Black-and-white is defined as pure white with prominent black patches on the head and body (no ratio of white-to-black is specified or favored). Tri-color is described as mostly white with some brown markings and dustings of black on the body and head. A honey bear tri-color has light brown with black tips that gradually fades to an off-white or lemon color. The tri-color loses the most color of any of the color varieties, usually becoming mostly white with possibly some champagne markings and a dusting of black hairs on the ears and/or body.
Afghan wedding
The next song that follows is “Hena Beyarin ba Dastash Gozarain” and Henna ("Kheena" by Afghans, a dark-red colored dye which leaves an orange-red color on the skin) is placed on their hands.
Arab wedding
In modern times, particularly those not living in Palestine, the henna night remains traditional in customs, but is very similar to a bachelorette party; the bride's female friends and relatives join her in celebrating, which includes food, drinks, and a lot of dancing. A women's group plays Arabic music, sometimes Islamic music, while everyone dances. A woman draws henna or mehndi, a temporary form of skin decoration using henna, on the bride and guests' skin — usually the palms and feet, where the henna color will be darkest because the skin contains higher levels of keratin there, which binds temporarily to lawsone, the colorant of henna.
Tattoo ink
Another ink may be used instead of black henna. "Jagua", a fruit based ink proven to be a healthier alternative to black henna.
Hair coloring
Alternative hair coloring products are designed to create hair colors not typically found in nature. The available colors are diverse, such as the colors green and fuchsia.
Permanent alternatives in some colors are available. Some color shades are blacklight-reactive, and thus show up under certain nightclub lighting, for instance.
Sienna
There is no single agreed standard for the colour of sienna, and the name is used today for a wide variety of hues and shades. They vary by country and colour list, and there are many proprietary variations offered by paint companies. The colour box at the top of the article shows one variation from the ISCC-NBS colour list.
Color
The ability of the [[human eye]] to distinguish colors is based upon the varying sensitivity of different cells in the [[retina]] to light of different [[wavelengths]]. Humans are [[Trichromacy|trichromatic]]—the retina contains three types of color receptor cells, or [[cone cell|cones]]. One type, relatively distinct from the other two, is most responsive to light that is perceived as blue or blue-violet, with wavelengths around 450 [[nanometre|nm]]; cones of this type are sometimes called "short-wavelength cones", "S cones", or "blue cones". The other two types are closely related genetically and chemically: "middle-wavelength cones", "M cones", or "green cones" are most sensitive to light perceived as green, with wavelengths around 540 nm, while the "long-wavelength cones", "L cones", or "red cones", are most sensitive to light is perceived as greenish yellow, with wavelengths around 570  nm.
Natural dye
A variety of plants produce red dyes, including avocado pits, a number of lichens, henna, alkanet or dyer's bugloss ("Alkanna tinctoria"), asafoetida and dyer's madder "Rubia tinctorum". Madder and related plants of the genus "Rubia" are native to many temperate zones around the world, and were already used as sources of good red dye, such as rose madder, in prehistory. Madder has been identified on linen in the tomb of Tutankhamun, and Pliny the Elder records madder growing near Rome. Madder was a dye of commercial importance in Europe, being cultivated in the Netherlands and France to dye the red coats of military uniforms until the market collapsed following the development of synthetic alizarin dye in 1869. Madder was also used to dye the "hunting pinks" of Great Britain.
Natural Color System
Hering argued that yellow is not a "redgreen" but a unique hue. Colorimetrist Jan Koenderink, in a critique of Hering's system, considered it inconsistent not to apply the same argument to the other two subtractive primaries, cyan and magenta, and see them as unique hues as well, not a "greenblue" or a "redblue". He also pointed out the difficulty within a four color theory that the primaries would not be equally spaced in the color circle; and the problem that Hering does not account for the fact that cyan and magenta are brighter than green, blue and red, whereas this is elegantly explained within the CMYK-model. He concluded that Hering's scheme fitted common language better than color experience.
Lawsonia inermis
The henna plant is native to northern Africa, western and southern Asia, and northern Australia, in semi-arid zones and tropical areas. It produces the most dye when grown in temperatures between . During the onset of precipitation intervals, the plant grows rapidly, putting out new shoots. Growth subsequently slows. The leaves gradually yellow and fall during prolonged dry or cool intervals. It does not thrive where minimum temperatures are below . Temperatures below will kill the henna plant.
Fancy rat
Color names can vary for more vaguely defined varieties, like lilac and fawn, while the interpretations of standards can fluctuate between (and even within) different countries or clubs.
Further dividing the varieties of fancy rats are the many different markings. Pet rats can appear in any combination of colors and markings. The markings are typically in reference to the patterns and ratios of colored hair versus white hair. Two extremes would be a self (completely solid, non-white color) and a Himalayan (completely white except blending into colored areas at the nose and feet, called points, as in a Himalayan cat's markings).
Color vision
The characteristic colours are, from long to short wavelengths (and, correspondingly, from low to high frequency), red, orange, yellow, green, blue, and violet. Sufficient differences in wavelength cause a difference in the perceived hue; the just-noticeable difference in wavelength varies from about 1 nm in the blue-green and yellow wavelengths, to 10 nm and more in the longer red and shorter blue wavelengths. Although the human eye can distinguish up to a few hundred hues, when those pure spectral colors are mixed together or diluted with white light, the number of distinguishable chromaticities can be quite high.
Chicken eyeglasses
Elmer Haas of the National Band & Tag Company, a major producer of rose-colored chicken eyeglasses, whose grandfather had "devised wire frames for chickens in 1902", indicated that he believed the purported blood-masking effect of the rose coloring was a myth: "the firm added the rose colored glasses because it indulged the chicken owners ... [c]hickens are color blind". (In fact, chickens, like other birds, have good color vision.) The firm had added the rose-colored feature to its glasses in 1939 under the brand name "Anti-Pix". This variety of eyeglasses was more complicated than others because the red lenses were fixed to a hinge at the top of the frame. This meant that as the hen lowered its head to feed, the lens swung out giving the hen an unobstructed view of the ground. When the hen raised her head, as she would during aggression, the lens would swing down giving the hen a red tinted perception of the environment.
Lawsone
Lawsone (2-hydroxy-1,4-naphthoquinone), also known as hennotannic acid, is a red-orange dye present in the leaves of the henna plant ("Lawsonia inermis") as well as in the flower of water hyacinth ("Eichhornia crassipes"). Humans have used henna extracts containing lawsone as hair and skin dyes for more than 5000 years. Lawsone reacts chemically with the protein keratin in skin and hair, in a process known as Michael addition, resulting in a strong permanent stain that lasts until the skin or hair is shed. The darker colored ink is due to more lawsone-keratin interactions occurring, which evidently break down as the concentration of lawsone decreases and the tattoo fades. Lawsone strongly absorbs UV light, and aqueous extracts can be effective sunless tanning and sunscreens. Chemically, lawsone is similar to juglone, which is found in walnuts.
Hair care
Most permanent color changes require that the cuticle of the hair be opened so the color change can take place within the cuticle. This process, which uses chemicals to alter the structure of the hair, can damage the cuticle or internal structure of the hair, leaving it dry, weak, or prone to breakage. After the hair processing, the cuticle may not fully close, which results in coarse hair or an accelerated loss of pigment. Generally, the lighter the chosen color from one's initial hair color, the more damaged it may be. Other options for applying color to hair besides chemical dyes include the use of such herbs as henna and indigo, or choosing ammonia-free solutions.
Calluna
Formerly heather was used to dye wool yellow and to tan leather. With malt, heather is an ingredient in gruit, a mixture of flavourings used in the brewing of heather-beer during the Middle Ages before the use of hops. Thomas Pennant wrote in "A Tour in Scotland" (1769) that on the Scottish island of Islay "ale is frequently made of the young tops of heath, mixing two thirds of that plant with one of malt, sometimes adding hops". The use of heather in the brewing of modern heather beer is carefully regulated. By law, the heather must be cleaned carefully before brewing, as the undersides of the leaves may contain a dusting of an ergot-like fungus, which is a hallucinogenic intoxicant.
Magenta
In color printing, the color called process magenta, pigment magenta, or printer's magenta is one of the three primary pigment colors which, along with yellow and cyan, constitute the three subtractive primary colors of pigment. (The secondary colors of pigment are blue, green, and red.) As such, the hue magenta is the complement of green: magenta pigments absorb green light; thus magenta and green are opposite colors.
List of colors by shade
Orange is the color in the visible spectrum between red and yellow with a wavelength around 585 – 620 nm. In the HSV color space, it has a hue of around 30°.
Lawsonia inermis
Henna is a tall shrub or small tree, standing . It is glabrous and multi-branched, with spine-tipped branchlets. The leaves grow opposite each other on the stem. They are glabrous, sub-sessile, elliptical, and lanceolate (long and wider in the middle; average dimensions are 1.5–5.0 cm x 0.5–2 cm or 0.6–2 in x 0.2–0.8 in), acuminate (tapering to a long point), and have depressed veins on the dorsal surface. Henna flowers have four sepals and a calyx tube, with spread lobes. Its petals are obvate, with white or red stamens found in pairs on the rim of the calyx tube. The ovary is four-celled, long, and erect. Henna fruits are small, brownish capsules, in diameter, with 32–49 seeds per fruit, and open irregularly into four splits.
Diamond (gemstone)
In contrast to yellow or brown hues, diamonds of other colors are more rare and valuable. While even a pale pink or blue hue may increase the value of a diamond, more intense coloration is usually considered more desirable and commands the highest prices. A variety of impurities and structural imperfections cause different colors in diamonds, including yellow, pink, blue, red, green, brown, and other hues. Diamonds with unusual or intense coloration are sometimes labeled "fancy" in the diamond industry. Intense yellow coloration is considered one of the fancy colors, and is separate from the color grades of white diamonds. Gemologists have developed rating systems for fancy colored diamonds, but they are not in common use because of the relative rarity of such diamonds.
Honey
Honey is classified by its floral source, and divisions are made according to the packaging and processing used. Also, regional honeys are identified. In the USA, honey is also graded on its color and optical density by USDA standards, graded on the Pfund scale, which ranges from 0 for "water white" honey to more than 114 for "dark amber" honey.
Ochre
During the Renaissance, yellow and red ochre pigments were widely used in painting panels and frescoes. The colours vary greatly from region to region, depending upon whether the local clay was richer in yellowish limonite or reddish hematite. The red earth from Pozzuoli near Naples was a salmon pink, while the pigment from Tuscany contained manganese, making it a darker reddish brown called terra di siena, or sienna earth.
Henna
The U.S. FDA has not approved henna for direct application to the skin. It is, however grandfathered in as a hair dye, and can only be imported for that purpose. Henna imported into the U.S. that appears to be for use as body art is subject to seizure, but prosecution is rare. Commercial Henna products that are adulterated often claim to be 100% natural on product packaging in order to pass import regulations in other countries.
Henna
"Henna" can also refer to the temporary body art resulting from the staining of the skin from the dyes (see also mehndi). Henna has been used since antiquity to dye skin, hair and fingernails, as well as fabrics including silk, wool and leather. Historically, henna was used in the Arabian Peninsula, Indian Subcontinent, near and Middle East, Carthage, other parts of North Africa and the Horn of Africa. The name is used in other skin and hair dyes, such as "black henna" and "neutral henna", neither of which is derived from the henna plant.
Highlighter
Many highlighters come in bright, often fluorescent and vibrant colors. Being fluorescent, highlighter ink glows under black light. The most common color for highlighters is yellow, but they are also found in orange, red, pink, purple, blue, and green varieties. Some yellow highlighters may look greenish in colour to the naked eye. Yellow is the preferred color to use when making a photocopy as it will not produce a shadow on the copy. Yet, the use of different colour highlighters simultaneously can systematically make information even more organized and readable and in high contrast.
Henna
In Ancient Egypt, Ahmose-Henuttamehu (17th Dynasty, 1574 BCE): Henuttamehu was probably a daughter of Seqenenre Tao and Ahmose Inhapy. Smith reports that the mummy of Henuttamehu's own hair had been dyed a bright red at the sides, probably with henna.
Dobermann
Two different color genes exist in the Dobermann: one for "black" (B) and one for "color dilution" (D). There are nine possible combinations of these alleles, which can result in four different color phenotypes: black, blue, red, and fawn (a.k.a. Isabella). The traditional and most common color occurs when both the color and dilution genes have at least one dominant allele (i.e., BBDD, BBDd, BbDD or BbDd) and is commonly referred to as "black", "black and rust," or "black and tan". The "red", "red rust," or "brown" coloration occurs when the black gene has two recessive alleles but the dilution gene has at least one dominant allele (i.e., bbDD, bbDd). The "blue" Dobermann has the color gene with at least one dominant allele and the dilution gene with both recessive alleles (i.e., BBdd or Bbdd). The "fawn" coloration is the least common, occurring only when both the color and dilution genes have two recessive alleles (i.e., bbdd). Thus, the blue color is a diluted black, and the fawn color is a diluted red.
Sienna
Raw sienna is a yellowish-brown natural earth pigment, composed primarily of iron oxide hydroxide. The box shows the colour of the pigment in its natural, or raw state. It contains a large quantity of iron oxide and a small quantity (about five percent) of manganese oxide.
Nail polish
In Egypt, the lower classes wore pale colors, whereas high society painted their nails a reddish brown color, with henna. Mummified pharaohs also had their nails painted with henna.
Magenta
Starting in 1935 the family of quinacridone dyes was developed. These have colors ranging from red to violet, so nowadays a quinacridone dye is often used for magenta. Various tones of magenta—light, bright, brilliant, vivid, rich, or deep—may be formulated by adding varying amounts of white to quinacridone artist's paints.
Henna
Though traditional henna artists were Nai caste in India, and barbering castes in other countries (lower social classes), talented contemporary henna artists can command high fees for their work. Women in countries where women are discouraged from working outside the home can find socially acceptable, lucrative work doing henna. Morocco, Mauritania, Yemen, Libya, Somalia, Sudan, the United Arab Emirates India and many other countries have thriving women's henna businesses. These businesses are often open all night for Eid, Diwali and Karva Chauth. Many women may work together during a large wedding, wherein hundreds of guests have henna applied to their body parts. This particular event at a marriage is known as the Mehndi Celebration or Mehndi Night, and is mainly held for the bride and groom.
Henna
For Moroccan Jews, a wedding festival can last up to 5 days, with 2 days involving henna art. One of these days is referred to as azmomeg (meaning unknown), and is the Thursday before the wedding where guests are invited to apply henna to the bride. The other henna ceremony occurs after the wedding ceremony, called the Day of Henna. On this day, typically an older woman applies henna to the bride after she dips in the mikveh to ward off evil spirits who may be jealous of the newlyweds. The groom is also painted with henna after the wedding. During the groom's henna painting, he commonly wears black clothing, this tradition emerged from the Pact of Umar as the Jews were not permitted to dress similar to colorful Muslim dress in Morocco.
Henna
Whole, unbroken henna leaves will not stain the skin. Henna will not stain skin until the lawsone molecules are made available (released) from the henna leaf. However, dried henna leaves will stain the skin if they are mashed into a paste. The lawsone will gradually migrate from the henna paste into the outer layer of the skin and bind to the proteins in it, creating a stain.
Since it is difficult to form intricate patterns from coarsely crushed leaves, henna is commonly traded as a powder made by drying, milling and sifting the leaves. The dry powder is mixed with one of a number of liquids, including water, lemon juice, strong tea, and other ingredients, depending on the tradition. Many artists use sugar or molasses in the paste to improve consistency to keep it stuck to the skin better. The henna mix must rest between 1 to 48 hours before use in order to release the lawsone from the leaf matter. The timing depends on the crop of henna being used. Essential oils with high levels of monoterpene alcohols, such as tea tree, cajeput, or lavender, will improve skin stain characteristics. Other essential oils, such as eucalyptus and clove, are also useful but are too irritating and should not be used on skin.
The paste can be applied with many traditional and innovative tools, starting with a basic stick or twig. In Morocco, a syringe is common. A plastic cone similar to those used to pipe icing onto cakes is used in the Indian culture. In the Western world, a cone is common, as is a Jacquard bottle, which is otherwise used to paint silk fabric. A light stain may be achieved within minutes, but the longer the paste is left on the skin, the darker and longer lasting the stain will be, so it needs to be left on as long as possible. To prevent it from drying or falling off the skin, the paste is often sealed down by dabbing a sugar/lemon mix over the dried paste or adding some form of sugar to the paste. After time the dry paste is simply brushed or scraped away. The paste should be kept on the skin for a minimum of 4 to 6 hours. but longer times and even wearing the paste overnight is a common practice. Removal should not be done with water, as water interferes with the oxidation process of stain development. Cooking oil may be used to loosen dry paste.
Henna
Back at the henna party, the bride sits on stage while family members and friends come up to her to have their palms marked with blots of henna. These marks represent many the long-lasting marriage as henna remains for many days. It also represents the blood from breaking the hymen upon consummating the marriage on the wedding night. Others add that the red stain on the hands of the guests are to mislead the evil spirits of the Jinn who are looking for the bride. After the painting, the party ends after lasting about 4 or 5 hours.
Roman hairstyles
Dying hair was popular among women, although the frequency that hair was coloured often made it weaker. Tertullian discusses how hair dye burnt the scalp and was harmful for the head. Artificial dyes could be applied through powders, gels and bleach. Henna, a temporary dye, or even animal fat, could be applied to make the hair more manageable. Aside from henna, more common permanent dyes were based on natural substances and perhaps more unorthodox mixtures. To prevent graying some Romans wore a paste at night made from herbs and earthworms and pigeon dung was used to lighten hair. For example, to dye hair black, Pliny the Elder suggests applying leeches that have rotted in red wine for 40 days.
Heron
The bill is generally long and harpoon-like. It can vary from extremely fine, as in the agami heron, to thick as in the grey heron. The most atypical bill is owned by the boat-billed heron, which has a broad, thick bill. The bill, as well as other bare parts of the body, is usually yellow, black, or brown in colour, although this can vary during the breeding season. The wings are broad and long, exhibiting 10 or 11 primary feathers (the boat-billed heron has only nine), 15–20 secondaries. and 12 rectrices (10 in the bitterns). The feathers of the herons are soft and the plumage is usually blue, black, brown, grey, or white, and can often be strikingly complex. Amongst the day herons, little sexual dimorphism in plumage is seen (except in the pond-herons); differences between the sexes are the rule for the night herons and smaller bitterns. Many species also have different colour morphs. In the Pacific reef heron, both dark and light colour morphs exist, and the percentage of each morph varies geographically. White morphs only occur in areas with coral beaches.
Henna
"Neutral henna" does not change the color of hair. This is not henna powder; it is usually the powder of the plant "Senna italica" (often referred to by the synonym "Cassia obovata") or closely related "Cassia" and "Senna" species.
Han purple and Han blue
Han purple fades in acid, so colorless particles found in pigments containing Han blue and Han purple may be particles which were originally purple, but which faded in acidic conditions in burial.
In addition, Han blue has fungicidal properties, so preserves better. Han purple reacts with oxalic acid to form BaCu(CO). The light blue color of this salt may explain the light blue color of some of the Terracotta Warriors' trousers – the color resulting from the presence of oxalate-excreting lichens.
Megaherb
Growing alongside the megaherbs are other plants, such as hebes, daisies, amber sedge, and three species of gentian: "Gentianella cerina" (giant gentian), growing to tall with flowers across, varying in colour from white to pale pink, red and purple; "Gentianella antarctica" and "Gentianella concinna", both with pinkish red flowers.
Henna
"Black henna" powder may be derived from indigo (from the plant "Indigofera tinctoria"). It may also contain unlisted dyes and chemicals such as "para"-phenylenediamine (PPD), which can stain skin black quickly, but can cause severe allergic reactions and permanent scarring if left on for more than 2–3 days. The FDA specifically forbids PPD to be used for this purpose, and may prosecute those who produce black henna. Artists who injure clients with black henna in the U.S. may be sued for damages.
Orange (colour)
The colour of robes also varies somewhat among the different "vehicles," or schools of Buddhism, and by country, depending on their doctrines and the dyes available. The monks of the strict Vajrayana, or Tantric Buddhism, practised in Tibet, wear the most colourful robes of saffron and red. The monks of Mahayana Buddhism, practised mainly in Japan, China and Korea, wear lighter yellow or saffron, often with white or black. Monks of Hinayana Buddhism, practised in Southeast Asia, usually wear ochre or saffron colour. Monks of the forest tradition in Thailand and other parts of Southeast Asia wear robes of a brownish ochre, dyed from the wood of the jackfruit tree.
In Europe and America orange and yellow are the colours most associated with amusement, frivolity and entertainment. In this regard, orange is the exact opposite of its complementary colour, blue, the colour of calm and reflection. Mythological paintings traditionally showed Bacchus (known in Greek mythology as Dionysus), the god of wine, ritual madness and ecstasy, dressed in orange. Clowns have long worn orange wigs. Toulouse-Lautrec used a palette of yellow, black and orange in his posters of Paris cafes and theatres, and Henri Matisse used an orange, yellow and red palette in his painting, the "Joy of Living". 
Orange is the colour most easily seen in dim light or against the water, making it, particularly the shade known as safety orange, the colour of choice for life rafts, life jackets or buoys. Highway temporary signs about construction or detours in the United States are orange, because of its visibility and its association with danger.
Muhammad Abu Tir
One of Abu Tir's most noticeable physical attributes and trademarks is his bright orange beard. The orange is actually a dyed substance called henna, a natural dyestuff, which needs to be applied periodically in order to maintain its lustrous colour. In an interview with the Israeli Channel 10 television Abu Tir stated that he had decided to dye his beard with henna because the prophet Muhammad had done so and also because it was a remedy for headaches and dandruff. Islam bans the use of black hair dyes; however, there is no mention of a ban on the use of other colours. Residents in his native village of Umm Tuba say that his signature beard does help him stand out when he is out campaigning at public events and functions.
Fuchsia (color)
The first synthetic dye of the color fuchsia, called fuchsine, was patented in 1859 by François-Emmanuel Verguin. It was later renamed magenta, and became highly popular under that name. 
In the system of additive colors, the RGB color model used to create all the colors on a computer or television display, the colors magenta and fuchsia are exactly the same, and have the same hex number, #FF00FF. The name fuchsia is used on the HTML web color list for this color, while the name magenta is used on the X11 web color list. They are both composed the same way, by combining an equal amount of blue and red light at full brightness, as shown in the image on the left.
Hydrangea
In most species the flowers are white, but in some species (notably "H. macrophylla"), can be blue, red, pink, light purple, or dark purple. In these species the color is affected by the presence of aluminium ions which are available or tied up depending upon the soil pH. For "H. macrophylla" and "H. serrata" cultivars, the flower color can be determined by the relative acidity of the soil: an acidic soil (pH below 7), will have available aluminum ions and typically produce flowers that are blue to purple, whereas an alkaline soil (pH above 7) will tie up aluminum ions and result in pink or red flowers. This is caused by a color change of the flower pigments in the presence of aluminium ions which can be taken up into hyperaccumulating plants. Lowering the pH of potting soils or mixes usually does not change the flower color to blue, because these soils have no aluminum ions. The ability to blue or pink a hydrangea is also influenced by the cultivar. Some plants are selected for their ability to be blued, while others are bred and selected to be red, pink or white. The flower color of most other Hydrangea species is not affected by aluminum and cannot be changed or shifted. Hydrangeas also have a nickname called 'Change Rose'.
Henna
PPD sensitivity is lifelong. A person who has become sensitized through black henna tattoos may have future allergic reactions to perfumes, printer ink, chemical hair dyes, textile dye, photographic developer, sunscreen and some medications. A person who has had a black henna tattoo should consult their physician about the health consequences of PPD sensitization.
Oxy-fuel welding and cutting
The hoses are color-coded for visual identification. The color of the hoses varies between countries. In the United States, the oxygen hose is green and the fuel hose is red. In the UK and other countries, the oxygen hose is blue (black hoses may still be found on old equipment), and the acetylene (fuel) hose is red. If liquefied petroleum gas (LPG) fuel, such as propane, is used, the fuel hose should be orange, indicating that it is compatible with LPG. LPG will damage an incompatible hose, including most acetylene hoses.
Albert Henry Munsell
Munsell Hue is the attribute of color by which we distinguish red from green, blue from yellow, and other colors. Munsell chose several colors to be the principal hues. These are Red, Yellow, Green, Blue, and Purple. These hues were arranged in a circle. Each hue can be mixed with the same amount of the neighboring hues to create intermediate hues: yellow-red, green-yellow, blue-green, purple-blue, and red-purple. Each color can be defined by how much of each principal hue it contains. A color that is composed of just a principal hue would be given a number 5. So, the red primary would be given the number 5R. If you move to the left of the red hue, the number increases, with the color exactly in between red and yellow-red defined as 10R. Continuing around the circle, the number of the color goes back down to 1YR right after 10 red, until the color is composed of just the yellow-red primary, in which case the color would be 10YR. So, the number represents how much of the primary hue the color contains.
Henna
The different words for henna in ancient languages imply that it had more than one point of discovery and origin, as well as different pathways of daily and ceremonial use.
Henna has been used to adorn young women's bodies as part of social and holiday celebrations since the late Bronze Age in the eastern Mediterranean. The earliest text mentioning henna in the context of marriage and fertility celebrations comes from the Ugaritic legend of Baal and Anath, which has references to women marking themselves with henna in preparation to meet their husbands, and Anath adorning herself with henna to celebrate a victory over the enemies of Baal.
Wall paintings excavated at Akrotiri (dating prior to the eruption of Thera in 1680 BCE) show women with markings consistent with henna on their nails, palms and soles, in a tableau consistent with the henna bridal description from Ugarit. Many statuettes of young women dating between 1500 and 500 BCE along the Mediterranean coastline have raised hands with markings consistent with henna. This early connection between young, fertile women and henna seems to be the origin of the Night of the Henna, which is now celebrated worldwide.
Shades of red
Varieties of the color red may differ in hue, chroma (also called saturation, intensity, or colorfulness) or lightness (or value, tone, or brightness), or in two or three of these qualities. Variations in value are also called tints and shades, a tint being a red or other hue mixed with white, a shade being mixed with black. A large selection of these various colors is shown below.
Somaliland
An important form of art in Somali culture is henna art. The custom of applying henna dates back to antiquity. During special occasions, a Somali woman's hands and feet are expected to be covered in decorative mendhi. Girls and women usually apply or decorate their hands and feet in henna on festive celebrations like Eid or weddings. The henna designs vary from very simple to highly intricate. Somali designs vary, with some more modern and simple while others are traditional and intricate. Traditionally, only women apply it as body art, as it is considered a feminine custom. Henna is not only applied on the hands and feet but is also used as a dye. Somali men and women alike use henna as a dye to change their hair colour. Women are free to apply henna on their hair as most of the time they are wearing a hijab.
