Abstract
Aspects of the present invention relate to systems and methods for color image hue shifting. Some aspects relate to processes by which reference hue values and corresponding hue shift values are used to modify color hue values in a non-perceptually-uniform color space. Some aspects relate to processes that generate a hue shift table for modifying image hue values.
