Abstract:
1. A method for matching a target color with a sample color, the method comprising the steps of: A. generating a target identifier that identifies a target color in a device independent color space; B. providing a set of color space distances based on (i) the target identifier and (ii) a set of sample identifiers that identifies a set of sample colors in the device independent color space, wherein each sample identifier defines a sample color area having a core area and a buffer area adjacent the core area, wherein the core area of the sample color area defined by each sample identifier includes a unique set of colors, and wherein the buffer area of the sample color area defined by each sample identifier is a same common color; and C. selecting, from the set of sample identifiers, a particular sample identifier that identifies a particular sample color based on the set of color space distances, in order to match the target color with the particular sample color.
