Quickly remove a color cast
The Fast Color Corrector and the Three-Way Color Corrector effects have controls to quickly balance colors so the
white, grays, and black are neutral. The adjustment that neutralizes the color cast in a sampled area is applied to the
entire image. This can remove the color cast in all colors. For example, if an image has an undesirable bluish cast, when
you sample an area that should be white, the White Balance control adds yellow to neutralize the bluish cast. This
yellow adjustment is added to all the colors in the scene, which should remove the color cast in the entire scene.
