In colorimetry, the Munsell color system is a color space that specifies colors based on three properties of color: hue (basic color), chroma (color intensity), and value (lightness). It was created by Professor Albert H. Munsell in the first decade of the 20th century and adopted by the United States Department of Agriculture (USDA) as the official color system for soil research in the 1930s. Several earlier color order systems had placed colors into a three-dimensional color solid of one form or another, but Munsell was the first to separate hue, value, and chroma into perceptually uniform and independent dimensions, and he was the first to illustrate the colors systematically in three-dimensional space. The system consists of three independent properties of color which can be represented cylindrically in three dimensions as an irregular color solid: 1)hue, measured by degrees around horizontal circles 2) chroma, measured radially outward from the neutral (gray) vertical axis 3)value, measured vertically on the core cylinder from 0 (black) to 10 (white) . . . #soilchemistry #soils #colour #experiments #study #global #instadaily (at Central Soil Salinity Research Institute) https://www.instagram.com/p/CG7CvEOnQwc/?igshid=171ao3a6lbm17
