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.
Color science is the scientific study of color including lighting and optics; measurement of light and color; the physiology, psychophysics, and modeling of color vision; and color reproduction. It is the modern extension of traditional color theory .
Light spectrum, from Theory of Colours – Goethe observed that colour arises at the edges, and the spectrum occurs where these coloured edges overlap.. Theory of Colours (German: Zur Farbenlehre) is a book by Johann Wolfgang von Goethe about the poet's views on the nature of colours and how they are perceived by humans.
In practice, the human color receptors will be saturated or even be damaged at extremely high light intensities, but such behavior is not part of the CIE color space and neither is the changing color perception at low light levels (see: Kruithof curve). The most saturated colors are located at the outer rim of the region, with brighter colors ...
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]
Newton's theory asserts that each prismatic color is 1/7 of the whole of light. If an infinite number, instead of seven, of light rays is assumed, then each color would be an infinitely small fraction of the whole of light. Schopenhauer's theory, however, claims that yellow is ¾ as bright as white.
Second corollary: such identical appearing lights must have identical effects when subtracted (i.e., filtered) from a mixture of light. Fourth law; The intensity of a mixture of lights is the sum of the intensities of the components. This is also known as Abney's law. These laws entail an algebraic representation of colored light.

In part correct, [2] being able to successfully explain refraction, reflection, rectilinear propagation and to a lesser extent diffraction, the theory would fall out of favor in the early nineteenth century, as the wave theory of light amassed new experimental evidence. [3] The modern understanding of light is the concept of wave-particle duality.
