The Colour Corrector includes tools that provide precise control over colour values. You can modify luma ranges in a clip (shadows, midtones, and highlights), sample colours, and adjust the colour balance. You can rewire colour channels and suppress colours, as well as animate a colour correction by manipulating the animation curve in the Channel Editor.
You can enter the Colour Corrector from some other Smoke modules such as Action and the Keyer. The Colour Corrector is particularly useful for removing colour spills in the Keyer. If you enter the Colour Corrector from a module, you are returned to that module when you exit the Colour Corrector.
You can also access the Colour Warper from the Colour Corrector. The Colour Warper works in parallel with the Colour Corrector—you can colour correct clips with the Colour Corrector and Colour Warper and then compare the results. Each setup is saved separately. For more information, see Colour Warper.
