Claim One:
1. A color processor comprising: a conversion source color data acquiring part that acquires a conversion source color dataset in a first color space; a color data pair acquiring part that acquires color data pairs each composed of a color dataset in the first color space and a color dataset in a second color space that is a conversion destination color space, the color dataset in the first color space and the color dataset in the second color space being both used to calculate a color conversion characteristic model specifying a correspondence between a color in the first color space and a color in the second color space; a color conversion characteristic model calculator that assigns weight to the color dataset in the first color space included in corresponding one of the color data pairs acquired by the color data pair acquiring part, according to a color difference distance between the color dataset in the first color space and the conversion source color dataset acquired by the conversion source color data acquiring part, and calculates the color conversion characteristic model by use of color data pairs each including a weighted color dataset in the first color space; and an evaluation value calculator that calculates an evaluation value indicating an evaluation on influence of the color data pairs on color conversion accuracy of the color conversion characteristic model, the color conversion characteristic model calculator adjusting the weight to be assigned to the color dataset in the first color space according to the evaluation value calculated by the evaluation value calculator, when calculating the color conversion characteristic model.
