Almost every tool in Fusion can be limited through use of an alpha channel connected to the blue EffectMask input of the node. You can use the alpha of an element, or you can make a custom alpha using one of the Mask nodes such as Polygon, BSpline, Rectangle or Ellipse, or you can use a Keyer node or a Bitmap node to create an alpha from an image or footage.
This is the rough draft of a chapter from a book about compositing with Fusion:

There's some information specifically about tracking and using masks on a color correction. It works the same way for most other tools, too.
