Abstract
A method for attenuation of near-neutral image colors is described. The pixel chroma is determined. A chroma control point is determined. A pixel color is shifted toward neutral. An imaging device that is configured for attenuation of near-neutral image colors is described. The imaging device includes a processor. The imaging processing device includes memory in electronic communication with the processor. Instructions are stored in the memory. The instructions are executable to determine pixel chroma. The instructions are also executable to determine a chroma control point. The instructions are further executable to shift a pixel color toward neutral.
