ABSTRACT:
A method and apparatus for converting color includes converting the hue, lightness, and/or saturation of first color data representing each of plurality of colors forming a color image, to produce second color data corresponding to the first color data. The second color data is converted to third color data suitable for the color space which can be expressed by the image output device used for the output of the color image. Color contraction which is conventionally associated with color conversion that increases lightness or saturation can be prevented.
