Color theory is rooted in antiquity, with early musings on color in Aristotle's (d. 322 BCE) On Colors and Claudius Ptolemy's (d. 168 CE) Optics.The influence of light on color was investigated and revealed further by al-Kindi (d. 873) and Ibn al-Haytham (d. 1039).
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.
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.
If the light is not a pure white source (the case of nearly all forms of artificial lighting), the resulting spectrum will appear a slightly different color. Red paint, viewed under blue light, may appear black. Red paint is red because it scatters only the red components of the spectrum. If red paint is illuminated by blue light, it will be ...
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 produce the illusion of a cyan square.

Thomas Young and Hermann von Helmholtz assumed that the eye's retina consists of three different kinds of light receptors for red, green and blue.. The Young–Helmholtz theory (based on the work of Thomas Young and Hermann von Helmholtz in the 19th century), also known as the trichromatic theory, is a theory of trichromatic color vision – the manner in which the visual system gives rise to ...
“It’s less of a color theory moment, and more that red has not been trending ... of incorporating red in an item, like a picture frame, light fixture, or lampshade, when the usual color choice ...
The work outlines the theory that all colors (yellow, red, purple, blue, and green) are derived from mixtures of black and white. On colors had a pronounced impact on subsequent color theories and remained influential until Isaac Newton's experiments with light refraction.
