## Discussion

A filter  that changes color values. Color adjustment filters are used to eliminate color casts, adjust hue, and correct brightness and contrast. Color adjustment filters do not perform color management; ColorSync performs color management. You can use Quartz 2D to specify the color space associated with an image. For more information, see [Color Management Overview](https://developer.apple.com/library/archive/documentation/GraphicsImaging/Conceptual/csintro/csintro_intro/csintro_intro.html#//apple_ref/doc/uid/TP30001148) and [Quartz 2D Programming Guide](https://developer.apple.com/library/archive/documentation/GraphicsImaging/Conceptual/drawingwithquartz2d/Introduction/Introduction.html#//apple_ref/doc/uid/TP30001066).
