Abstract
Color contributions from one or more light sources to scene entities are separated from the scene entities' respective unilluminated colors. This enables the color contributions of light sources as well as scene entities' unilluminated colors to be adjusted or modified independently of each other. Light source color contributions may be combined by groups of light sources, by light source to scene entity interaction, and/or by light source type. Adjustments to light source color contributions and/or unilluminated colors may be performed using a saturation varying color space or general tone mapping techniques. The light source color contributions and unilluminated colors of scene entities may be employed in contexts including an image processing application and within or as a shader of a renderer.
