Abstract:
A color reproduction method comprises: inputting a first color gamut and a second color gamut; applying, to the first color gamut, a first color correction in which color adaptation is taken into consideration on a basis of reference white in the first color gamut and the second color gamut and a second color correction for matching basic colors in the first color gamut and the second color gamut with each other; applying, to a first color gamut to which the first color correction and the second color correction are applied, a third color correction for correcting a color that is present in colors outside of the second color gamut to colors on a surface or inside of the second color gamut; and generating color conversion information for converting the first color gamut into the second color gamut.
