In formal color theory, purple colors often refer to the colors on the line of purples on the CIE chromaticity diagram (or colors that can be derived from colors on the line of purples), i.e., any color between red and violet, not including either red or violet themselves.
Red-violet refers to a rich color of high medium saturation about 3/4 of the way between red and magenta, closer to magenta than to red. In American English, this color term is sometimes used in color theory as one of the purple colors—a non- spectral color between red and violet that is a deep version of a color on the line of purples on the ...
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.

In some British authoritative texts the term purple refers to any mixture of red and blue, suggesting the color term purple covers the full range between red and blue in the United Kingdom. In other texts it is the term violet that covers the same full range of colors.
Violet is closely associated with purple. In optics, violet is a spectral color (referring to the color of different single wavelengths of light), whereas purple is the color of various combinations of red and blue (or violet) light, [5] [6] some of which humans perceive as similar to violet.
Modern color theory uses either the RGB additive color model or the CMY subtractive color model, and in these, the complementary pairs are red–cyan, green–magenta (one of the purples), and blue–yellow. In the traditional RYB color model, the complementary color pairs are red–green, yellow–purple, and blue–orange.
Limenitis arthemis, the red-spotted purple or white admiral, is a North American butterfly species in the cosmopolitan genus Limenitis. It has been studied for its evolution of mimicry , and for the several stable hybrid wing patterns within this nominal species ; it is one of the most dramatic examples of hybridization between non-mimetic and ...
Purpura (/ ˈ p ɜːr p jʊər ə /) is a condition of red or purple discolored spots on the skin that do not blanch on applying pressure. The spots are caused by bleeding underneath the skin secondary to platelet disorders, vascular disorders, coagulation disorders, or other causes.
