The brilliant iridescent colors of the peacock's tail feathers are created by structural coloration, as first noted by Isaac Newton and Robert Hooke.. Structural coloration in animals, and a few plants, is the production of colour by microscopically structured surfaces fine enough to interfere with visible light instead of pigments, although some structural coloration occurs in combination ...

Color theory, or more specifically traditional color theory, is a historical body of knowledge describing the behavior of colors, namely in color mixing, color contrast effects, color harmony, color schemes and color symbolism. [1] Modern color theory is generally referred to as color science.
The observer then perceives a cyan (or magenta) square on the blank sheet. This complementary color afterimage is more easily explained by the trichromatic color theory (Young–Helmholtz theory) than the traditional RYB color theory; in the opponent-process theory, fatigue of pathways promoting red produces the illusion of a cyan square. [39]
If the reflectance spectrum of a color is 1 (100%) for all the wavelengths between A and B, and 0 for all the wavelengths of the other half of the color space, then that color is a maximum chroma color, semichrome, or full color (this is the explanation to why they were called semichromes). Thus, maximum chroma colors are a type of optimal color.
One way of posing their relationship is in terms of whether they posit colors as sui generis properties (properties of a special kind that can't be reduced to more basic properties or constellations of such). This divides color primitivism from color reductionism. A primitivism about color is any theory that explains colors as irreducible ...
Basic Color Terms: Their Universality and Evolution (1969; ISBN 1-57586-162-3) is a book by Brent Berlin and Paul Kay. Berlin and Kay's work proposed that the basic color terms in a culture, such as black, brown, or red, are predictable by the number of color terms the culture has. All cultures have terms for black/dark and white/bright.
The four pigments in a bird's cone cells (in this example, estrildid finches) extend the range of color vision into the ultraviolet. [1]Tetrachromacy (from Greek tetra, meaning "four" and chroma, meaning "color") is the condition of possessing four independent channels for conveying color information, or possessing four types of cone cell in the eye.
