Ok I was viewing someones short clip they did. First they greenscreened themselves and then dropped himself into the scene in episode 2 when they are fighting in the arena at the end. He said he did they keying in AE and then said he sampled a color from the background and did a color overlay on himself to make it look more like he fits in the scene. Basically a color correction. Does anyone know how to do a color overlay in AE?
