The Munsell color system, showing: a circle of hues at value 5 chroma 6; the neutral values from 0 to 10; and the chromas of purple-blue (5PB) at value 5. In colorimetry, the Munsell color system is a color space that specifies colors based on three properties of color: hue (basic color), value ( lightness ), and chroma (color intensity).
Albert Henry Munsell (January 6, 1858 – June 28, 1918) was an American painter, teacher of art, and the inventor of the Munsell color system . He was born in Boston, Massachusetts, [ 1] attended and served on the faculty of Massachusetts Normal Art School, and died in nearby Brookline . As a painter, he was noted for seascapes and portraits.
Munsell Color Company. The Munsell Color Company was founded by Albert H. Munsell in 1917 with two other stockholders, Arthur Allen and Ray Greenleaf. [1] It was located at Boston, Massachusetts. This company was manufactured to carry on business by publishing books, selling color supplies for schools such as crayons, water colors, paper colors ...
The Farnsworth–Munsell 100 Hue Color Vision test is a color vision test often used to test for color blindness. The system was developed by Dean Farnsworth in the 1940s and it tests the ability to isolate and arrange minute differences in various color targets with constant value and chroma that cover all the visual hues described by the ...
OSA-UCS. In colorimetry the OSA-UCS (Optical Society of America Uniform Color Scales) is a color space first published in 1947 and developed by the Optical Society of America ’s Committee on Uniform Color Scales. [1] Previously created color order systems, such as the Munsell color system, failed to represent perceptual uniformity in all ...
A color in a color space is defined as a combination of its primaries, where each primary must give a non-negative contribution. Any color space based on a finite number of real primaries is incomplete in that it cannot reproduce every color within the gamut of the standard observer.
In colorimetry and color appearance models, lightness is a prediction of how an illuminated color will appear to a standard observer. While luminance is a linear measurement of light, lightness is a linear prediction of the human perception of that light. This distinction is meaningful because human vision's lightness perception is non-linear ...
The concept of a color system with a hue was explored as early as 1830 with Philipp Otto Runge's color sphere. The Munsell color system from the 1930s was a great step forward, as it was realized that perceptual uniformity means the color space can no longer be a sphere. As a convention, the hue for red is set to 0° for most color spaces with ...
