Abstract: 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.

Abstract: The system provides for controlling color reproduction of input color image data in a network having nodes (or sites). The system distributes the input color image data from one of the nodes to other nodes, and provides data structures in the network. The system has means for providing color calibration data at each node characterizing output colors (colorants) of the rendering device of the node, and means for producing at each node, responsive to the color calibration data of the rendering device of the node, information for transforming the input color image data into output color image data at the rendering device of the node. The rendering device of each node renders a color reproduction responsive to the output color image data, wherein colors displayed in the reproduction at the rendering device of each node appear substantially the same within the output colors attainable by the rendering devices.
