  abstract = {{A} new approach to relationships between soil color and soil spectral properties is studied using colorimetric concepts. {S}pectral reflectance of 84 highly varied soil samples was determined in the laboratory with a spectrophotometer. {C}olors were also visually estimated using {M}unsell soil color charts. {T}he comparison between chromaticity coordinates computed from the spectral reflectance curves, and {M}unsell color converted into the same coordinates, showed good agreement. {T}hus, the color aspect of a soil sample can be predicted from its spectral reflectance. {U}sually the reverse is not true, as two objects with the same color aspect may have different reflectance curves. {T}his phenomenon, known as metamerism, was observed only once among our soil samples. {T}his allowed us to use a multiple linear regression model to predict the visible reflectance curve from the {M}unsell color. {W}ith these results, soil spectral properties can be estimated from colors noted in the field. {T}his has numerous applications in remote sensing.
