The Munsell color product is a color system that specifies colors according to three color dimensions, hue, value, and chroma (difference from gray with 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”, which would use decimal notation as an alternative to color names (which 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 color chart is still 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 bring about an achromatic mixture.
The program is made up of an irregular cylinder using the value axis (light/dark) running down and up through it, along with the axis from the earth.
Dark colors are at the end of the tree and light at the very top, measured from 1 (dark) to 10 (light).
Each horizontal “slice” from the cylinder all over the axis is really a hue circle, that he split 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 those ten hues, and after that referring to the angle inside them from 1 to 10.
“Chroma” was measured out of the center from the wheel, with lower chroma being less saturated (washed out, such as pastels). Keep in mind that there is no intrinsic upper limit to chroma. Different areas of the color space have different maximal chroma coordinates. As an illustration 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 an array of possible chroma levels, as well as a chroma of 10 might or might not be maximal dependant upon the hue and value.
One is fully specified by 85dexupky three of the numbers. As an example a rather saturated blue of medium lightness would be 5B 5/10 with 5B meaning the hue in the center of the blue hue band, 5/ meaning medium lightness, and a chroma of 10.
The initial embodiment of the system (the 1905 Atlas) had some deficiencies as being a physical representation of your theoretical system. These were improved significantly inside the 1929 Munsell Book of Color and thru a substantial combination of experiments done by the Optical Society of America from the 1940’s contributing to the notations (sample definitions) for that modern Munsell Book of Color. The machine is still widely used in a number of applications and represents one of the best available data sets around 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 depending on standard samples. Commonly used in practical applications like painting and textiles.
Disadvantages: Complementary colors will not be on opposite sides, to ensure one cannot predict the outcomes of color mixing well.
