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.

Color Vision in Color Display Night Vision Goggles
Aerospace Medicine and Human Performance, 2017INTRODUCTION: Aircrew viewing eyepiece-injected symbology on color display night vision goggles (CDNVGs) are performing a visual task involving color under highly unnatural viewing conditions. Their performance in discriminating different colors and responding to color cues is unknown.METHODS: Experimental laboratory measurements of 1) color ...

, 1994 Color blind individuals see many fewer colors than do people with normal color vision. Among color blind people there is tremendous variation in the capacity for color vision, ranging from no color vision to nearly normal color vision. Keywords: color vision deficiency; cone photoreceptors; red–green color vision; congenital color vision ...

Publisher Summary Color vision is the ability to discriminate changes in the wavelength composition of a visual stimulus independently of its effective intensity. It is an ability that humankind shares with many other species, including insects, amphibians, reptiles, fish, and birds as well as other mammals.

Journal of Physiology-Paris, 2012
In neurogeometry, principles of differential geometry and neuron dynamics are used to model the representation of forms in the primary visual cortex, V1. This approach is well-suited for explaining the perception of illusory contours such as Kanizsa's figure (see Petitot (2008) for a review). In its current version, neurogeometry uses achromatic inputs

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.

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.

Ophthalmologica, 1980
The results of pseudoisochromatic tests (TMC Ishihara, AOH-R-R) are relatively independent of age. In the Panel D-15, the NCT box 6/4 and the desaturated panel, ageing goes hand in hand with blue-yellow confusions. Fault-positive red-green confusions result from D8/2 examination. For the FM 100 Hue test and the Anomaloscope Nagel, the data found in the
