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.
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.
For example, by some definitions, it would be impossible to use Goethe's color wheel for analogous colors, because they do not share a common color, such as blue-green. If you wanted to use the analogous colors blue, blue-green, and green with Boutet's color wheel on the left, you wouldn't be able to. [1]

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.
A RYB color wheel with tertiary colors described under the modern definition. RYB is a subtractive mixing color model, used to estimate the mixing of pigments (e.g. paint) in traditional color theory, with primary colors red, yellow, and blue. The secondary colors are green, purple, and orange as demonstrated here:
Among their other color pairs, brown (#282800) on dark green (#A0A000) has a contrast ratio of 3.24:1, which is less than the WCAG recommendation, dark brown (#1E1E00) on light green (#B9B900) has a contrast ratio of 4.54:1 and blue (#00007D) on yellow (#FFFF00) has a contrast ratio of 11.4:1. The colors named in the report use different color ...
The equivalent color on a computer to the pigment color red-violet shown above would be this electric purple, i.e. the much brighter purple reproduced on the screen of a computer. This color is pure purple conceived as computer artists conceive it, as the color on the color wheel halfway between color wheel violet and electric magenta. Thus ...
