Well, by not having my monitor with me on an interview and not doing a white balance on the natural light coming through the window, I've ended up with some horrible green hues in the hair of my subject and also what I'm going to call here, some flaring of green hues on his shirt. I've yet to purchase final cut pro 5 which I intend to do soon, and am wondering if I'll be able to do color correction for my problem adequatly with it? It really needs to look good to great. I hope I can get it there somehow. Thanks

Use the 3 way color correction filter. It should correct your problem.
