Sure, no prob

Just for future reference, you never really want to do anything in an editing app other than editing.
You always want to do your post work in a post app, etc

In After Effects in general, add an "Adjustment Layer(s)" to correct the overall color of your shot.

If your camera is moving, then a small amount of targeted grading/color corection may be required so as to not over-color certain parts of the footage.

If you like, as I do this for a living, I would be more than happy to help you do the color work for you if you feel you want to concentrate on other things.

Just an option

Otherwise, another alternative for you is if you can get me an uncompressed single still frame I can do a generic color grade and create an After Effects preset for you that is specific to your overall spot that you can simply apply to a master adjustment layer and render.

Up to you.

Lemme know
