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 method is empirical and based on determination of colour by visual comparison of fossil specimens to the Geological Society of America Rock-Color Chart (Munsell colour system) under a binocular microscope. The FCI values 0 to 10 are indicated below:
The Munsell color system. The image shows: * The neutral values in steps of 1 from 0 to 10 * A circle of 10 hues at value 5 and chroma 6 * The chromas of purple-blue in steps of 2 from 0 to 12, at value 5 The colors should be
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.

In 1939, the system's approach was published in the Journal of Research of the National Bureau of Standards, and the ISCC formally approved the system, which consisted of a set of blocks within the color space defined by the Munsell color system as embodied by the Munsell Book of Color. Over the following decades, the ISCC–NBS system's ...
Albert Henry Munsell (January 6, 1858 – June 28, 1918) was an American painter, teacher of art, and the inventor of the Munsell color system.. He was born in Boston, Massachusetts, [1] attended and served on the faculty of Massachusetts Normal Art School, and died in nearby Brookline.
The colour of a rock or its component parts is a distinctive characteristic of some rocks and is always recorded, sometimes against standard colour charts, such as that produced by the Rock-Color Chart Committee of the Geological Society of America based on the Munsell color system.
A visual value can be approximated by the help of the neutral gray chips of the Rock or Soil Color chart with ten intervals. The color parameters can be expressed with figures semi-quantitatively as: hue, value/chroma (H, V/C). The color "medium red" should serve as an example for presentation with the three color attributes, 5R 5.5/6.
