The Munsell color system is a color system that specifies colors based upon three color dimensions, hue, value, and chroma (difference from gray at the 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”, and therefore would use decimal notation instead of color names (which he felt were “foolish” and “misleading”). He first started work towards the program in 1898 and published it entirely form colored Notation in 1905. The munsell color chart continues to be 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 using the value axis (light/dark) running up and down through it, as does the axis in the earth.
Dark colors are in the bottom from the tree and light at the very top, measured from 1 (dark) to 10 (light).
Each horizontal “slice” of the cylinder across the axis is really a hue circle, which 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, then talking about the angle inside them from 1 to 10.
“Chroma” was measured outside the center of your wheel, with lower chroma being less saturated (washed out, such as pastels). Keep in mind that there is not any intrinsic upper limit to chroma. Different regions of colour space have different maximal chroma coordinates. As an example light yellow colors have significantly more potential chroma than light purples, as a result of nature in the eye and the physics of color stimuli. This led to an array of possible chroma levels, along with a chroma of 10 may or may not be maximal dependant upon the hue and value.
One is fully specified by 85dexupky the three numbers. For example a rather saturated blue of medium lightness would be 5B 5/10 with 5B meaning colour in the middle of the blue hue band, 5/ meaning medium lightness, along with a chroma of 10.
The very first embodiment of the system (the 1905 Atlas) had some deficiencies as being a physical representation in the theoretical system. They were improved significantly from the 1929 Munsell Book of Color and through a thorough series of experiments carried out by the Optical Society of America inside the 1940’s causing the notations (sample definitions) to the modern Munsell Book of Color. The system continues to be popular in a range of applications and represents one of the better available data sets in the perceptual scaling of lightness, chroma and hue.
Advantages: A somewhat simple system for comparing colors of objects by assigning them a set of numbers based on standard samples. Traditionally used in practical applications including painting and textiles.
Disadvantages: Complementary colors usually are not on opposite sides, to ensure that one cannot predict the outcomes of color mixing perfectly.
