Color harmony complying reproducible color palettes

A computer system comprising:

• a processor;
• a storage coupled to the processor;
• and
• an instruction set stored on the storage to cooperate with the processor and storage to:
• receive data representative of a color palette, the color palette comprising a plurality of colors with predefined color harmony rules based on relative positions of the colors in a color space;
• receive a reproducible color gamut for a rendering system on which image data comprising colors of the color palette is to be reproduced;
• determine an irreproducible color of the color palette outside the rendering system's reproducible color gamut;
• and
• provide a color gamut mapping algorithm that is configured to determine, based on the reproducible color gamut, a suggested color for a replacement color palette also complying with the predefined color harmony rules to bring the color palette towards being within the rendering system's reproducible color gamut;
• and
• iteratively use the replacement color palette as the color palette until it is determined that all colors of the replacement color palette are inside a rendering system's reproducible color gamut.
