Title: Mapping an input color value in an input color space to an output color value in an output color space

Abstract: A method and system for mapping an input color value in an input color space to an output color value in an output color space comprising a lookup table mapping an input value to an output color value, the lookup table having n number of possible values for a first fixed color component and q number of possible values for a second fixed color component, wherein q and a number m of possible values for t color components in the input color space are less than n. Surrounding input values are determined in the lookup table in a t dimensional space, wherein each surrounding input value has a same value for the fixed color component(s). Surrounding output values to which the surrounding input values map are determined. The determined input and output surrounding values and the input value are used to estimate an output value corresponding to the received input value.
