A spectral reflectance storage unit stores spectral reflectance data on each of a plurality of predetermined colors; spectral distribution data storage contains spectral distribution data on a light source; an arithmetic unit determines XYZ values of each of the colors under specified viewing conditions, based on the spectral distribution data of the light source under the viewing conditions as well as on the spectral reflectance data on each of the colors, the spectral distribution data stored in the spectral distribution data storage; and a profile dependent on the viewing conditions is created based on the XYZ values of the colors obtained by the arithmetic unit.
