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 ( lightness ), and chroma (color intensity).
For example Munsell value 0 is pure black, and value 10 is pure white. Colors with a discernible hue must therefore have values in between these extremes. In a subtractive color model (e.g. paint, dye, or ink) lightness changes to a color through various tints, shades, or tones can be achieved by adding white, black, or grey respectively.
Gradient Munsell hue wheel at value 5 and constant chroma (6.24) Munsell Hue is the attribute of color by which we distinguish red from green, blue from yellow, and other colors. Munsell chose several colors to be the principal hues. These are Red, Yellow, Green, Blue, and Purple. These hues were arranged in a circle.
The chromaticity coefficients were chosen "on the basis of the spacing of the Munsell system. A lightness difference ΔW = 1 is assumed to correspond to a chromaticness difference √ ΔU 2 + ΔV 2 = 13 (approximately)." [4] With the coefficients thus selected, the color difference in CIEUVW is simply the Euclidean distance:
The Munsell color system includes the following three components: [1] Hue: indicates the dominant spectral (i.e., rainbow) color, which in the soil is generally yellow or red. Each page of the Munsell soil color book displays a different hue. Examples include 10YR, 5YR, and 2.5Y. Value: indicates lightness or darkness. The value increases from ...
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 of perceptual responses, he realized that no symmetrical shape would do, so he reorganized his ...
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.
