American Journal of Ophthalmology, 1924
This is a brief presentation of theories of color vision as based on four primary colors, red, yellow, green and blue. The way in which these may be associated to give other color effects is illustrated by diagrams. Read before the Utah Ophthalmological Society, May 19th, 1924.

Schopenhauer on vision and the colors
Documenta Ophthalmologica, 1997Arthur Schopenhauer (1788-1860) published his book, On Vision and the Colors in 1816. He started from Aristotle's linear color system and Goethe's three pairs of contrast colors. His work preceded Hering's theory of opponent colors but his path to insight was blocked by his anti-Newtonianism and his neo-Hellenistic attitude toward science.

Eye design in invertebrates is diverse and gives rise to a variety of color-vision systems. The most sophisticated color vision has been found in marine crustaceans - mantis shrimps. These shrimps use for color vision 12 spectrally different photoreceptors, while many other crustaceans have only two types of spectrally selective photoreceptors ...

Scientific American, 1989
Three centuries of experimentation in optics, psychophysics and biochemistry established the dependence of color vision on three kinds of light-absorbing molecules, or pigments, in the cone cells of the retina. The author has isolated the genes that encode the pigments and has identified genetic anomalies that lead to color blindness.

Journal of the Optical Society of America, 1955
In the theory described the three variables of the Young-Helmholtz theory are replaced by I, s, and σ, the area, position, and breadth of a probability distribution. As far as color mixing is concerned, the theory is equivalent to the Young-Helmholtz theory. It leads to the result that the spectrum locus on the chromaticity diagram should be a parabola

Color vision deficiencies are inherently intriguing. Perhaps beyond their importance for task performance based on visual discriminations is their significance for color theory. They are, as it were, nature’s “test“ cases.

Science, 1996
In the primate retina, three types of cone photoreceptors—red, blue, and green—code the color in the visual field. R. H. Masland describes what is known about how this information is processed in retinal cells and how new results in this issue of Science change our way of thinking about color vision.
