A color processing apparatus converts a target M-dimensional color signal in an input color space into an N-dimensional output color signal in an output color space. M and N are natural numbers and NM. The apparatus includes a first calculation unit and a second calculation unit. The first calculation unit uniquely calculates (N−M) colorants of the converted output color signal from the target color signal with using plural color-signal pairs. In each pair, corresponding one of the (N−M) colorants of an output color signal in the output color space are associated with an input color signal in the input color space. The second calculation unit calculates the M colorants of the converted output color signal from the target color signal and the (N−M) colorants of the converted output color signal.
