For color conversion of image data in a L*a*b* color space, a color conversion system includes a color conversion processor to implement a first color conversion for color conversion of data positions of an image data in a reference-color representing first region covering a constant hue line at a prescribed hue angle on an a*b* plane, and a second color conversion for color conversion of data positions of the image data in a second region set outside the first region within an angular range smaller in hue angle than the prescribed hue angle on the a*b* plane, the prescribed hue angle being set up in an angular region of 0 degree or more and 90 degree or less relative to an a* axis, the color conversion processor being adapted to implement mutually different color conversion processes for the first color conversion and the second color conversion.
