Summary:A method for color correcting an input color image having input color values adapted for display on a reference display device having a plurality of input color primaries to account to provide reduced observer metemaric failure on a narrow-band display device. A metamerism correction transform is applied to the input color image to determine an output color image having output color values in an output color space appropriate for display on the narrow-band display device. The metamerism correction transform modifies colorimetry associated with the input colors to provide output color values such that an average observer metameric failure is reduced for a distribution of target observers, and is formed responsive to a distribution of perceived color differences for a set of input colors that are determined for a set of target observers.
