Orange (colour)  Orange is the colour between yellow and red on the spectrum of visible light. Human eyes perceive orange when observing light with a dominant wavelength between roughly 585 and 620 nanometres. In painting and traditional colour theory, it is a secondary colour of pigments, created by mixing yellow and red. It is named after the fruit of the same name. The orange colour of carrots, pumpkins, sweet potatoes, oranges, and many other fruits and vegetables comes from carotenes, a type of photosynthetic pigment. These pigments convert the light energy that the plants absorb from the sun into chemical energy for the plants' growth. Similarly the hues of autumn leaves are from the same pigment after chlorophyll is removed. In Europe and America, surveys show that orange is the colour most associated with amusement, the unconventional, extroverts, warmth, fire, energy, activity, danger, taste and aroma, the autumn and Allhallowtide seasons, as well as having long been the national colour of the Netherlands and the House of Orange. It also serves as the political colour of Christian democracy political ideology and most Christian democratic political parties. In Asia it is an important symbolic colour of Buddhism and Hinduism. In English, the colour orange is named after the appearance of the ripe orange fruit. The word comes from the Old French "orange", from the old term for the fruit, "pomme d'orange". The French word, in turn, comes from the Italian "arancia", based on Arabic "nāranj" (), derived from the Sanskrit "nāraṅga" (नारङ्ग). The earliest known recorded use of "orange" as a colour name in English was in 1502, in a description of clothing purchased for Margaret Tudor. Another early recorded use was in 1512, in a will now filed with the Public Record Office. The place-name "Orange" has a separate etymology and is not related to that of the colour. Prior to this word's being introduced to the English-speaking world, "saffron" already existed in the English language. "Crog" also referred to the saffron colour, so that orange was also referred to as "ġeolurēad" ("yellow-red") for reddish orange, or "ġeolucrog" ("yellow-saffron") for yellowish orange. Alternatively, orange things were sometimes described as red such as red deer, red hair, the Red Planet and robin redbreast.
