摘要：
A color conversion device includes a non-basic-color value determiner that determines a value of a non-basic color, to be used in an image forming unit, different from a basic color based on a maximum value for the non-basic color usable relative to an input basic-color value in an input image signal having the basic color as an element, a first non-basic-color limit rate and a second non-basic-color limit rate set relative to the input basic-color value and a total input basic-color value, respectively, and each indicating a rate that limits the use of the non-basic color relative to the maximum value; and a basic-color value determiner that determines a value of the basic color to be used in the image forming unit based on the determined non-basic-color value. The determiners convert the input image signal into an output image signal having the basic and non-basic colors as elements.
