Vader's saber seems pink. I know that's vague and cliché, but I'm throwing that out there as a general impression.

Could the reds have been toned down too much in that scene? The laser flashes and smoke seems pinkish in the shootout immediately following the duel, whereas the GOUT in the corner is more of a red.

Also, you can see more of that 'blue spill' I was talking about in the short shot where Luke yells, "NO!" toward Vader and Ben. It's present all over the '04 transfer, so it's probably non-reparable.
