The Munsell color product is a color system that specifies colors based upon three color dimensions, hue, value, and chroma (difference from gray in a given hue and lightness).
Professor Albert H. Munsell, an artist, wanted to create a “rational way to describe color” in line with the principle of “perceived equidistance”, and that would use decimal notation rather than color names (that he felt were “foolish” and “misleading”). He first started focus on the device in 1898 and published it completely form colored Notation in 1905. The munsell color chart remains used today.
Munsell constructed his system around a circle with ten segments, arranging its colors at equal distances and selecting them in such a manner that opposing pairs would lead to an achromatic mixture.
The machine includes an irregular cylinder using the value axis (light/dark) running down and up through it, along with the axis in the earth.
Dark colors are at the bottom of your tree and light-weight on the top, measured from 1 (dark) to 10 (light).
Each horizontal “slice” of the cylinder throughout the axis is really a hue circle, that he divided into five principal hues: red, yellow, green, blue, and purple, five intermediates, yellow-red, green-yellow, blue-green, purple-blue, and red-purple.
Munsell hue is specified by selecting one of these brilliant ten hues, then discussing the angle inside them from 1 to 10.
“Chroma” was measured out of the center in the wheel, with lower chroma being less saturated (washed out, like pastels). Be aware that there is not any intrinsic upper limit to chroma. Different areas of the color space have different maximal chroma coordinates. For example light yellow colors have significantly more potential chroma than light purples, due to nature of your eye and also the physics of color stimuli. This led to a variety of possible chroma levels, and a chroma of 10 might or might not be maximal based on the hue and value.
One is fully specified by 85dexupky the three numbers. As an example a reasonably saturated blue of medium lightness could be 5B 5/10 with 5B meaning colour during the blue hue band, 5/ meaning medium lightness, and a chroma of 10.
The very first embodiment of your system (the 1905 Atlas) had some deficiencies being a physical representation from the theoretical system. These were improved significantly in the 1929 Munsell Book of Color and thru a substantial combination of experiments done by the Optical Society of America from the 1940’s causing the notations (sample definitions) to the modern Munsell Book of Color. The device continues to be popular in a variety of applications and represents among the finest available data sets about the perceptual scaling of lightness, chroma and hue.
Advantages: A comparatively simple system for comparing colors of objects by assigning them a pair of numbers according to standard samples. Commonly used in practical applications including painting and textiles.
Disadvantages: Complementary colors usually are not on opposite sides, to ensure one cannot predict the outcomes of color mixing very well.
