Claim One:
1. A method for adjusting image color values, said method comprising: a) dividing a first color gamut into a plurality of regions; b) defining control points at the vertices of said regions; c) selecting a target color, wherein said target color is defined by first target coordinates related to said first color gamut; d) determining a first color region, in said plurality of regions, where said first color is located; e) determining first color region control point coordinates for said control points corresponding to said first color region; f) determining a target color weighting vector using said first target coordinates and said first color region control point coordinates; g) converting said first color region control point coordinates to relate to a second color gamut thereby creating second-gamut control point coordinates; and h) calculating second-gamut target color coordinates related to said second color gamut by combining said target color weighting vector with said second-gamut control point coordinates.
