Abstract. Three approaches to the problem of interpolation of color spectrum locus line specified in tabulated form are considered: the first is based on interpolation in the space of color coordinates, the second uses interpolation in the space of chromaticity coordinates, and the third one utilizes interpolation of the spectral locus as some tabular curve having its specific shape. Mathematical relations describing the behavior of spectral gamut in the visible wavelengths range are derived.
Keywords: colorimetric standard, spectrum locus, chromaticity coordinates, interpolation, Bezier curve
