Abstract
In some implementations, a method provides color correction in images and includes determining multiple input groups of pixels of an image based on one or more pixel attributes of the pixels. Each of the input groups includes different pixels of the image than the other input groups. The method determines an individual neutral color associated with each of the input groups of pixels based on the colors of the pixels in the associated input group. An individual color correction associated with each of a number of output groups of pixels is determined based on one or more neutral colors associated with the input groups. The method applies each individual color correction to its associated output group of pixels, including adjusting the color of pixels in each output group to reduce color casts on the pixels.
