The total number of genes that contribute to eye color is unknown, but there are a few likely candidates. A study in Rotterdam (2009) found that it was possible to predict eye color with more than 90% accuracy for brown and blue using just six SNPs. [16] [17] In humans, eye color is a highly sexually dimorphic trait. [18]
An Ishihara test image as seen by subjects with normal color vision and by those with a variety of color deficiencies. A pseudoisochromatic plate (from Greek pseudo, meaning "false", iso, meaning "same" and chromo, meaning "color"), often abbreviated as PIP, is a style of standard exemplified by the Ishihara test, generally used for screening of color vision defects.
Thus human color perception is determined by a specific, non-unique linear mapping from the infinite-dimensional Hilbert space H color to the 3-dimensional Euclidean space R 3 color. Technically, the image of the (mathematical) cone over the simplex whose vertices are the spectral colors, by this linear mapping, is also a (mathematical) cone in ...
Vanishing plates: only individuals with normal color vision could recognize the figure. Hidden digit plates: only individuals with color vision defect could recognize the figure. Diagnostic plates: intended to determine the type of color vision defect (protanopia or deuteranopia) and the severity of it.
The Farnsworth–Munsell 100 Hue Color Vision test is a color vision test often used to test for color blindness.The system was developed by Dean Farnsworth in the 1940s and it tests the ability to isolate and arrange minute differences in various color targets with constant value and chroma that cover all the visual hues described by the Munsell color system.

A comparison between a typical normalized M cone's spectral sensitivity and the CIE 1931 luminosity function for a standard observer in photopic vision. In the CIE 1931 model, Y is the luminance, Z is quasi-equal to blue (of CIE RGB), and X is a mix of the three CIE RGB curves chosen to be nonnegative (see § Definition of the CIE XYZ color space).

The resulting color vision is simpler than typical human trichromatic color vision, and much simpler than tetrachromatic color vision, typical of birds and fish. A dichromatic color space can be defined by only two primary colors. When these primary colors are also the unique hues, then the color space contains the individuals entire gamut. In ...
