So I can track and change the color of eyes but I want to have an effect like the color is moving inside. Wether that's magic or fire you can find some videos on YouTube that look really nice. Is this possible with AE? If so, how do u get this effect? Ive been messing with some of it but have gone round and round and ended up with some crappy results. Any ideas?
This should be a pretty straightforward deal for you:
In the project window,d rag your eye footage clip onto the Make comp icon. Its settings now precisely match the eye footage in your comp.
In the new comp, turn the eye footage off and do whatever you want! Use a noise effect and vegas to make weired colors, add some fire footage, make fire of your own... whatever.
In the main comp, highlight your eye layer with the tracking applied. Option-drag (Mac) or Alt-drag (win) the new comp onto this layer. The new comp now replaces the eye footage, and you can tweak at will.

I addition to Dave's advice, here's a few things to try:
Use Find Edges combined with Matte Choker and Levels to create a organic looking matte the can help you comp/transition to your color. Add some Fractal Noise for complexity.
Work @ 32 bit and add a glow.
