Couple of things:

1. Adobe Premiere is a good candidate to do your editing/

2. Make sure your background screen is evenly lit. Uneven lighting can cause color variations and the software will see it as a different color.

3. Try to avoid harsh shadows on the background screen.

4. If you are planning on inserting your talent on a background plate, make sure your lighting matches the background plate. (I.E. look at the shadows for clues on the direction of the light source and try to match the shadows of the talent to it.)

I would recommend experimenting first and see what the results are...
