I love blue. Most of my clothes are blue like the sky!
What shade of blue is your favorite?
I love sea blue. DId you know that we see natural blues because of an optical effect called Rayleigh scattering?
I did not know that. What else about optical effect and colors? What other colors are different?
All of the primary colors. It occurs when light goes through transparent solids and liquids.
What are the primary colors?
Primary color
A set of primary colors is, most tangibly, a set of "real" colorants or colored lights that can be combined in varying amounts to produce a gamut of colors. This is the essential method used in applications that are intended to elicit the perception of diverse sets of color, e.g. electronic displays, color printing, and paintings. Perceptions associated with a given combination of primary colors are predicted by applying the appropriate mixing model (additive, subtractive, additive averaging, etc.) that embodies the underlying
Blue
Blue is one of the three primary colours of pigments in painting and traditional colour theory, as well as in the RGB colour model. It lies between violet and green on the spectrum of visible light. The eye perceives blue when observing light with a dominant wavelength between approximately 450 and 495 nanometres. Most blues contain a slight mixture of other colours; azure contains some green, while ultramarine contains some violet. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering.
