Abstract
Abstract A method for displaying blended colors on a variable visual display is performed within a system by selecting two or more base colors to be blended, displaying the base colors at edge portions of a geometic display region having a shape based on the number of colors being blended, choosing a given number of intermediate colors to be generated in the blend, and generating the intermediate colors based on the relative distance from each intermediate color to each base color and a biasing factor which allows a user to increase the range of potential shades for a selected intermediate color given the same base colors. The resulting blend is displayed within the geometric display region on the variable visual display for a user who is then able to alter the blend in real-time, and/or isolate and store shade(s) of intermediate color(s) for future use.
