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 ().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 classification systems exist: 1. Such a classification is more suitable for describing coarse-grained soils rather than clay soils whose properties are less dependent on the particle size distribution. This classification is based on the percentages of sand, silt and clay Sizes making up the soil. per page. 14.330 SOIL MECHANICS Soil Classification SOIL CLASSIFICATION BASICS Commonly based on grain size and soil consistency.

Soil classification is the grouping of soils with similar engineering properties into a category by using the results of laboratory-based index tests, e.g., group name and symbol (ASTM D 2487, AASHTO M 145). Other soil clumps assume a bright color because the soil was comparatively dry during other periods.
