The Munsell color product is one system that specifies colors based upon three color dimensions, hue, value, and chroma (difference from gray with a given hue and lightness).
Professor Albert H. Munsell, an artist, wanted to make a “rational strategy to describe color” based on the principle of “perceived equidistance”, and that would use decimal notation instead of color names (which he felt were “foolish” and “misleading”). He first started work on the system in 1898 and published it 100 % form colored Notation in 1905. The munsell soil color chart has become used today.
Munsell constructed his system around a circle with ten segments, arranging its colors at equal distances and selecting them in a manner that opposing pairs would lead to an achromatic mixture.
The device includes an irregular cylinder with all the value axis (light/dark) running all around through it, along with the axis from the earth.
Dark colors are towards the bottom of the tree and lightweight at the very top, measured from 1 (dark) to 10 (light).
Each horizontal “slice” of your cylinder all over the axis is actually a hue circle, which he separated 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 referring to the angle inside them from 1 to 10.
“Chroma” was measured out from the center from the wheel, with lower chroma being less saturated (washed out, like pastels). Note that there is absolutely no intrinsic upper limit to chroma. Different regions of the colour space have different maximal chroma coordinates. As an example light yellow colors have considerably more potential chroma than light purples, due to the nature in the eye along with the physics of color stimuli. This resulted in a wide range of possible chroma levels, along with a chroma of 10 might or might not be maximal according to the hue and value.
One is fully specified by 85dexupky the 3 numbers. For instance a rather saturated blue of medium lightness can be 5B 5/10 with 5B meaning colour during the blue hue band, 5/ meaning medium lightness, plus a chroma of 10.
The initial embodiment of your system (the 1905 Atlas) had some deficiencies being a physical representation in the theoretical system. They were improved significantly inside the 1929 Munsell Book of Color and thru an extensive group of experiments performed by the Optical Society of America inside the 1940’s leading to the notations (sample definitions) for the modern Munsell Book of Color. The system remains widely used in a range of applications and represents one of the better available data sets in 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 based upon standard samples. Popular in practical applications for example painting and textiles.
Disadvantages: Complementary colors are not on opposite sides, to ensure one cannot predict the outcome of color mixing very well.
