A method for enhancing a color image may include selecting a set of operations from a group of operations, specifying an order for performing the selected set of operations, receiving the color image, and performing, with a processor, the selected set of operations in the specified order on the color image. The group of operations may include a color correcting operation, an image filtering operation, a color linearization operation, a saturation adjustment operation, a luma scaling operation, and an image dithering operation. The method may include determining an optical property of an ambient light source or an image type of the color image. The selecting of the set of operations may be based at least in part on the determined optical property of the ambient light source or on the determined image type. The method may include an efficient method for correcting image saturation of a color image.
