The Munsell color method is a color system that specifies colors based upon three color dimensions, hue, value, and chroma (difference from gray at a given hue and lightness).
Professor Albert H. Munsell, an artist, wanted to generate a “rational strategy to describe color” based on 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 work towards the device in 1898 and published it entirely form in Color 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 way that opposing pairs would bring about an achromatic mixture.
The machine consists of an irregular cylinder together with the value axis (light/dark) running up and down through it, along with the axis of your earth.
Dark colors are in the bottom from the tree and light-weight at the top, measured from 1 (dark) to 10 (light).
Each horizontal “slice” in the cylinder all over the axis is a hue circle, which 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 ten hues, and then referring to the angle inside them from 1 to 10.
“Chroma” was measured out from the center of your wheel, with lower chroma being less saturated (washed out, such as pastels). Note that there is absolutely no intrinsic upper limit to chroma. Different aspects of the color space have different maximal chroma coordinates. As an example light yellow colors have considerably more potential chroma than light purples, because of the nature in the eye along with the physics of color stimuli. This led to a variety of possible chroma levels, and a chroma of 10 may or may not be maximal according to the hue and value.
One is fully specified by 85dexupky three of the numbers. As an example a relatively saturated blue of medium lightness could be 5B 5/10 with 5B meaning colour during the blue hue band, 5/ meaning medium lightness, along with a chroma of 10.
The very first embodiment from the system (the 1905 Atlas) had some deficiencies being a physical representation of your theoretical system. These were improved significantly within the 1929 Munsell Book of Color and thru a comprehensive combination of experiments carried out by the Optical Society of America from the 1940’s causing the notations (sample definitions) for the modern Munsell Book of Color. The program remains to be popular in a variety of applications and represents among the finest available data sets in the perceptual scaling of lightness, chroma and hue.
Advantages: A fairly 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 certainly not on opposite sides, so that one cannot predict the results of color mixing very well.
