Abstract: A first color component of a pixel or scene entity is modified using a color correction curve defined at least partly by a second color component of this pixel or entity. Each pixel or entity has its own separate color correction curve, independent of the color correction curves of other pixels or entities. The saturation value of a pixel or scene entity may be modified based on its luminance value. The luminance value determines a saturation gamma function curve, mapping the original saturation value of a pixel or entity to a new saturation value. The unilluminated color of a pixel or of an illuminated entity in a scene being rendered may also be taken into account. This output color may be stored in the appropriate pixel of an image or combined with colors from other portions of the scene being rendered.

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.
