1. A method for converting color image data comprising: identifying a first color device space, a second color device space, and an objective color space; and mapping a first gamut in the objective color space corresponding to the first color device space into a second gamut in the objective color space corresponding to the second color device space based on one or more polygons and distance ratios to generate a mapped first gamut, wherein the mapped first gamut is capable of being used for converting the color image data into output color image data.
