1. A color conversion system operable to convert color values in image data to a color space, the color conversion system comprising: a modeling module operable to generate a numerical model according to a radial basis function for converting the color values in the image data to the color space, wherein the numerical model includes error approximations operable to form the radial basis function into a linear process; and a color converter operable to convert the color values in the image data to the color space based on the numerical model.
