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.

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
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.
Color analysis can be conducted by-eye, usually matching specimen color with reference charts. This methodology has been used extensively in soil analysis, often using the Munsell color system as the reference. [1] [2] While this is a traditionally used method, it is considerably subjective, relying on the ability of the naked eye to match colors.
Another influential older cylindrical color model is the early-20th-century Munsell color system. Albert Munsell began with a spherical arrangement in his 1905 book A Color Notation, but he wished to properly separate color-making attributes into separate dimensions, which he called hue, value, and chroma, and after taking careful measurements ...
Cerebral achromatopsia can be diagnosed easily with color vision tests, commonly the Farnsworth-Munsell 100 hue test or the Ishihara plate test. [2] Testing and diagnosis for cerebral achromatopsia is often incomplete and misdiagnosed in doctor's offices.
All of these agents of deterioration hinder the effectiveness of the Munsell color system, which directly matches pigment shades. The Munsell color system is a scientific system in which colors have been ranged into a color fan based upon three attributes: hue or color, the chroma or color saturation, and the value or neutral lightness or darkness.
Munsell may refer to: Albert Henry Munsell (1858–1918), American painter, teacher of art, and the inventor of the Munsell color system; Harvey M. Munsell, American soldier in the Civil War.
