A color processor includes: an acquisition unit that acquires first and second multi-valued color signals respectively indicating in a multi-valued manner quantities of first and second color materials used for reproducing color with a specific hue, the second color material having a different density from the first color material; a generation unit that generates first and second binary color signals by performing dither processing, respectively with first and second dither matrices, for the first and second multi-valued color signals acquired by the acquisition unit, the second dither matrix having the same angle and the same number of lines as the first dither matrix and being used for forming halftone dots at positions different from positions of halftone dots formed by use of the first dither matrix; and an output unit that outputs to a print mechanism the first and second binary color signals generated by the generation unit.
