Abstract
A non-transitory machine readable medium that has a computer program for execution by at least one processing unit is described. The computer program receives a selection of a location on an image that includes several pixels. Each pixel has several color values. The computer program identifies a set of color values of a pixel that corresponds to the selected location on the image. Based on the identified set of color values, the computer program defines a custom color component that is defined by a fractional contribution from each of the plurality of primary color components of the color space. The computer program generates a response curve along the custom color component. The response curve corresponds a set of input color values of the custom color component to a set of output color values of the custom color component.
