The Munsell color technique is a color system that specifies colors according to three color dimensions, hue, value, and chroma (difference from gray at a given hue and lightness).
Professor Albert H. Munsell, an artist, wanted to produce a “rational approach to describe color” based on the principle of “perceived equidistance”, which would use decimal notation as an alternative to color names (that he felt were “foolish” and “misleading”). He first started work towards the device in 1898 and published it completely form colored Notation in 1905. The munsell soil 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 such a way 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, as does the axis of the earth.
Dark colors are towards the bottom of your tree and lightweight at the top, measured from 1 (dark) to 10 (light).
Each horizontal “slice” in the cylinder all over the axis is really a hue circle, which he split up 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 referring to the angle inside them from 1 to 10.
“Chroma” was measured outside the center of the wheel, with lower chroma being less saturated (washed out, such as pastels). Note that there is not any intrinsic upper limit to chroma. Different aspects of the color space have different maximal chroma coordinates. For instance light yellow colors have considerably more potential chroma than light purples, as a result of nature of your eye and also the physics of color stimuli. This generated an array of possible chroma levels, plus a chroma of 10 might or might not be maximal according to the hue and value.
A color is fully specified by 85dexupky the 3 numbers. For example a rather saturated blue of medium lightness would be 5B 5/10 with 5B meaning the colour in the center of the blue hue band, 5/ meaning medium lightness, and a chroma of 10.
The first embodiment from the system (the 1905 Atlas) had some deficiencies like a physical representation of the theoretical system. They were improved significantly in the 1929 Munsell Book of Color and thru a substantial number of experiments carried out by the Optical Society of America inside the 1940’s resulting in the notations (sample definitions) for the modern Munsell Book of Color. The machine remains traditionally used in a range of applications and represents one of the best available data sets in the perceptual scaling of lightness, chroma and hue.
Advantages: A relatively simple system for comparing colors of objects by assigning them a set of numbers based on standard samples. Widely used in practical applications such as painting and textiles.
Disadvantages: Complementary colors are certainly not on opposite sides, to ensure that one cannot predict the results of color mixing well.
