Colorimetry program, deals with the numerical acquisition of body colors. Its purpose is to evaluate the data supplied by so-called reflectance spectrophotometers according to the formula developed by the CIE (Commission International de Eclairage), which culminates in the representation of the measured body colors in the three-dimensional LAB color space. With explanation of the theory of colorimetry, which includes a derivation and presentation of the formula material used, and a series of reflectance spectra of various body colors as sample files.
