Patent ID: 7403205

Claim:
A method of transferring colors between color devices, the method comprising: establishing a source color gamut for a source device, the source color gamut having a white point, a black point, and primary points; establishing a destination color gamut for a destination device, the destination color gamut having a white point, a black point, and primary points; performing white and black point adaptation such that the source white point is mapped to the destination white point and the source black point is mapped to the destination black point, thereby establishing adapted white and black points; processing neutral points from the source color gamut to the destination color gamut; determining aimed primary points on an aimed gamut surface of an aimed gamut from the source and destination primary points, the destination gamut, and color preference; mapping important lines, using the determined aimed primary points, from the source gamut to the destination gamut; mapping gamut surface points from the source gamut to the destination gamut using the mapped important lines; and processing interior points of the source gamut surface.
