Munsell Soil Color Chart Views
In colorimetry, the Munsell color system is a color space that specifies colors based on three color dimensions: hue, value (lightness), and chroma (color purity). It was created by Professor Albert H. Munsell in the first decade of the 20th century and adopted by the USDA as the official color system for soil research in the 1930s.
Note that the Munsell Book of Color contains more color samples than this chart for both 5PB and 5Y (particularly bright yellows, up to 5Y 8.5/14), however they are not reproducible in the sRGB color space, which has a limited color gamut designed to match that of televisions and computer displays. Note also that there are no samples for values 0 (pure black) and 10 (pure white), which are theoretical limits not reachable in pigment, and no printed samples of value 1.
The original embodiment of the system (the 1905 Atlas) had some deficiencies as a physical representation of the theoretical system. These were improved significantly in the 1929 Munsell Book of Color and through an extensive series of experiments carried out by the Optical Society of America in the 1940s resulting in the notations (sample definitions) for the modern Munsell Book of Color. Though several replacements for the Munsell system have been invented, building on Munsell’s foundational ideas—including the Optical Society of America’s Uniform Color Scales, and the International Commission on Illumination’s CIELAB (L*a*b*) and CIECAM02 color models—the Munsell system is still widely used, by, among others, ANSI to define skin and hair colors for forensic pathology, the USGS for matching soil colors, in Prosthodontics during the selection of shades for dental restorations, and breweries for matching beer colors.[9][10]
