Patent ID: 8427498

Claim:
A computer implemented method for selecting colors comprising: associating, in dependence on a mathematical equation derived from measuring psychophysical responses of a plurality of test subjects to a first plurality of test colors, a color score with each of a second plurality of colors that are numerically defined in a color library; displaying on a visual user interface a combination of at least three colors from the color library; displaying on the visual user interface a combined color score for said color combination; wherein the combined color score is calculated using a controller as follows: (a) calculating for each unique pair of the color combination that are adjacent to each other an adjacent pair color score using a first equation in dependence on the color score of each color in the adjacent pair; (b) calculating for each unique pair of the color combination that are non-adjacent to each other a non-adjacent pair color score using a second equation in dependence of the color score of each color in the non-adjacent pair; (c) wherein the combined color score =1/n·(Σadjacent pair color score(s)+Σnon-adjacent pair color score(s)), where n is the total number of unique adjacent and non-adjacent pairs in the color combination.
