1. A method of image processing for mapping full-color images to highlight-color images comprising: (a) reading an input image; (b) sampling the image to obtain a sample color; (c) obtaining table access values from values that define the sample color; (d) using the table access values to access a first two-dimensional look-up table to determine an amount of a highlight color that corresponds to the sample color; (e) determining an amount of a base color that corresponds to the sample color; and, (f) rendering the image with the highlight and base colors in accordance with their determined amounts.
