Which method is NOT used for color correction in After Effects?

Keyframe tracking is primarily used for motion tracking and stabilization within After Effects, allowing users to track the movement of objects in a video clip over time. This technique helps apply effects or changes to specific areas of a shot based on the movement of objects, but it does not directly address color correction.

In contrast, layer blending modes, color keying, and adjustment layers are directly related to color correction processes. Layer blending modes allow users to change the way layers interact with each other, affecting how colors combine and produce various visual effects. Color keying involves removing specific colors from a scene or replacing them, which is a common technique for correcting or altering colors within a composition. Adjustment layers are used to apply color correction effects universally to all layers beneath them without altering those layers directly, thereby simplifying the workflow for achieving desired color effects.

Understanding the application of each technique clarifies why keyframe tracking does not function as a method for color correction in this context.
