Are you new to After Effects. The Effects>Color Correction>Change Color or Effects>Color Correction>Change to Color may be what you want. It all depends on the what the shot looks like. How consistent is the color? Without a screenshot it's really hard to give you more direction than I have given you. You can just drag a screenshot of the video to the reply field on this forum or print screen and paste.
If you are new to AE then plan to spend a couple of hours learning where the switches are and how to use the UI. The After Effects product page has some excellent getting started tutorials.
