Abstract
A color processing apparatus includes a first subtracting unit, a second subtracting unit, and an output unit. The first subtracting unit subtracts color values of CMY color signals corresponding to an achromatic color value from color values of input CMY color signals in accordance with replacement to the achromatic color value. The second subtracting unit subtracts color values of CMY color signals corresponding to a color value of an additional color signal different from the CMY color signals from the color values of the CMY color signals after the subtraction by the first subtracting unit in accordance with replacement to the color value of the additional color signal. The output unit multiplies the color values of the CMY color signals after the subtraction by the second subtracting unit and the color value of the additional color signal by N (N>1) and subsequently outputs the color signals.
