Claim:
1. A method for performing color conversion comprising: generating a perceptual color space value associated with an input pixel of input image data in a first color space, wherein the first color space is divided into a plurality of slices, input calibration vectors are defined for a first slice of the plurality of slices in a perceptual color space, and output calibration vectors are provided for the first slice of the perceptual color space; converting the input and output calibration vectors in the perceptual color space to a mapping in the first color space; generating a first color conversion matrix operator of the set of predetermined color conversion matrix operators based on the mapping in the first color space; determining, for the input pixel, one or more operators for converting input pixel values associated with the input pixel to output pixel values, wherein the operators comprise at least the first color conversion matrix operator selected from the set of predetermined color conversion matrix operators, wherein the first color conversion matrix operator is selected based at least in part on the perceptual color space value associated with the input pixel; and applying the one or more operators to the input pixel values in the first color space to generate the output pixel values, wherein output image data in the first color space comprises the output pixel values.
