This invention pertains to a computer-implemented method and program for the comparison of color gamuts.Using first and second collections of sample color points respective hulls are created in a color space. The set of all of the points disposed on the surface of the a hull or within the volume enclosed thereby represents the respective color gamut. The hulls are combined, preferably by a Boolean operation, to create a third hull in the color space representing at least one region of overlap or at least one region of exclusion between the first color gamut and the second color gamut. The volume of at least one of the hulls may be calculated and compared to the volume of the region of overlap and/or the region of exclusion.A visual display of the contour produced by the intersection of one or both of the hulls with a plane perpendicular to a predetermined reference line in the color space may be created to ascertain qualitatively the degree of alignment of the first and second hulls along the reference line. The determination of whether a given color point lies within a hull may also be made.
