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.

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.
Chromaticity is an objective specification of the quality of a color regardless of its luminance. Chromaticity consists of two independent parameters, often specified as hue (h) and colorfulness (s), where the latter is alternatively called saturation, chroma, intensity, [1] or excitation purity.
24-bit palette sample image 24 bit Palette Color Test Chart. This is a full list of color palettes for notable video game console hardware.. For each unique palette, an image color test chart and sample image (original True color version follows) rendered with that palette (without dithering unless otherwise noted) are given.
The Munsell color system, showing: a circle of hues at value 5 chroma 6; the neutral values from 0 to 10; and the chromas of purple-blue (5PB) at value 5. In colorimetry, the Munsell color system is a color space that specifies colors based on three properties of color: hue (basic color), value , and chroma (color intensity

The test color is a single spectral color, for which the subject can adjust the brightness. The mixture color combines two spectral colors, for which the subject can adjust the proportion, thereby changing the hue. These two colored lights are positioned side-by-side and the subject changes the two parameters until the colors appear to match ...
Unique hue is a term used in perceptual psychology of color vision and generally applied to the purest hues of blue, green, yellow and red. The proponents of the opponent process theory believe that these hues cannot be described as a mixture of other hues, and are therefore pure, whereas all other hues are composite. [ 1 ]
