Picture 2 looks great, Harmy. Picture 5 has a bit too much of a yellow cast in the highlights - the silver droid behind Threepio looks gold, and the walls look stained. 4 is too blue.

I really think these need to be color corrected scene-by-scene and not "overall," as it were.

I think I agree with you. The best method would be to color correct scene by scene. There seems to be no general setting that completely improves all scenes. However, Dark Jedi's method seems to come the closest.
