The Munsell color technique is one system that specifies colors based on three color dimensions, hue, value, and chroma (difference from gray in a given hue and lightness).
Professor Albert H. Munsell, an artist, wanted to produce a “rational way to describe color” in line with the principle of “perceived equidistance”, which would use decimal notation as opposed to color names (that he felt were “foolish” and “misleading”). He first started work on the program in 1898 and published it entirely form in Color Notation in 1905. The munsell soil 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 a manner that opposing pairs would result in an achromatic mixture.
The system contains an irregular cylinder together with the value axis (light/dark) running down and up through it, along with the axis from the earth.
Dark colors are towards the bottom from the tree and lightweight at the very top, measured from 1 (dark) to 10 (light).
Each horizontal “slice” of your cylinder throughout the axis is actually 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 brilliant ten hues, and after that talking about the angle inside them from 1 to 10.
“Chroma” was measured outside the center in the wheel, with lower chroma being less saturated (washed out, like pastels). Note that there is no intrinsic upper limit to chroma. Different regions of the color space have different maximal chroma coordinates. As an illustration light yellow colors have significantly more potential chroma than light purples, as a result of nature of the eye and the physics of color stimuli. This triggered an array of possible chroma levels, plus a chroma of 10 might or might not be maximal according to the hue and value.
One is fully specified by 85dexupky the three numbers. For example a rather saturated blue of medium lightness will be 5B 5/10 with 5B meaning colour during the blue hue band, 5/ meaning medium lightness, as well as a chroma of 10.
The initial embodiment of the system (the 1905 Atlas) had some deficiencies like a physical representation in the theoretical system. These were improved significantly in the 1929 Munsell Book of Color and through a substantial combination of experiments done by the Optical Society of America in the 1940’s contributing to the notations (sample definitions) for that modern Munsell Book of Color. The machine continues to be commonly used in a variety of applications and represents one of the better available data sets on the perceptual scaling of lightness, chroma and hue.
Advantages: A fairly simple system for comparing colors of objects by assigning them a collection of numbers based upon standard samples. Commonly used in practical applications such as painting and textiles.
Disadvantages: Complementary colors are certainly not on opposite sides, to ensure one cannot predict the results of color mixing very well.
