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.
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
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.
This means that 5R is located in the middle of the red hue, 5.5 is the lightness of Munsell value near the middle between light and dark, and 6 is the degree of the Munsell chroma, or the color saturation, which is about in the middle of the saturation scale. [2]
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. Munsell Color Company; Munsell color system developed by the company above Farnsworth-Munsell 100 hue test; Munsell, Missouri, a community in the United ...
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 ...
The only things left in the Munsell Color Company were the production of the Atlas papers, charts, disks and Munsell publications. At the same time, the Munsell Color Foundation and Munsell Color Laboratory moved to Baltimore, Maryland, where it was near to the National Bureau of Standards and Johns Hopkins University. [1]
