If you make a Qualifier (mask) in a Color node you can then modify any aspect of the selected colors with the various controls -- of which the Primary controls are most obvious.
So put your cursor in Edit over the clip in question (as long as no other clips above it), switch to the Color page, click on the eyedropper icon in the middle of the screen and sample your color area. You can adjust the sample in several ways. Then go to the left and use the Primary Wheels to change the area selected.
If you want to affect a different selection, make another color node in the node tree area, and repeat the process. If areas overlap, you may need to move beyond serial nodes (each one wired to the next one) to parallel nodes. (The Layer mixer is a lot like Photoshop's layers, in inverse order.)
Read the Color documentation and maybe take the Color tutorial on BMD's website.
