Abstract
A method and system for alternatingly applying different colors to a realistic computer generated graphic image while preserving the effects of shading, highlights, reflectors and other lighting effects. A user selects a 'New Color' to apply to an image and picks an 'Original Color' from the image in an area not subject to extreme lighting effects. The difference between the parameters of these two colors in (H,S,V) coordinates is determined and applied to every pixel in a segment of the image to calculate a replacement pixel color. Tools are provided to allow the user to divide an image into segments to which color modification can be individually applied.
