The Munsell color system is one system that specifies colors based upon three color dimensions, hue, value, and chroma (difference from gray in a given hue and lightness).
Professor Albert H. Munsell, an artist, wanted to make a “rational method to describe color” depending on the principle of “perceived equidistance”, and this would use decimal notation rather than color names (that he felt were “foolish” and “misleading”). He first started focus 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 bring about an achromatic mixture.
The device contains an irregular cylinder with the value axis (light/dark) running down and up through it, as does the axis of the earth.
Dark colors are in the bottom in the tree and light on the top, measured from 1 (dark) to 10 (light).
Each horizontal “slice” of the cylinder across the axis can be 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 these simple ten hues, and after that discussing the angle inside them from 1 to 10.
“Chroma” was measured right out of the center of your 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 colour space have different maximal chroma coordinates. As an illustration light yellow colors have considerably more potential chroma than light purples, because of the nature of the eye along with the physics of color stimuli. This generated a variety of possible chroma levels, along with a chroma of 10 may or may not be maximal depending on the hue and value.
One is fully specified by 85dexupky the three numbers. As an example a relatively saturated blue of medium lightness could be 5B 5/10 with 5B meaning the colour in the center of the blue hue band, 5/ meaning medium lightness, as well as a chroma of 10.
The initial embodiment from the system (the 1905 Atlas) had some deficiencies like a physical representation from the theoretical system. They were improved significantly inside the 1929 Munsell Book of Color and thru a thorough group of experiments performed by the Optical Society of America inside the 1940’s contributing to the notations (sample definitions) for the modern Munsell Book of Color. The device is still popular in many different 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 some numbers based upon standard samples. Commonly used in practical applications such as painting and textiles.
Disadvantages: Complementary colors will not be on opposite sides, to ensure one cannot predict the outcomes of color mixing perfectly.
