As for the colour of TIE fighters, I must say it is painfully obvious that the blue colour is the bluescreen leaking, in the GOUT you can clearly see the colour flickering all over the place with plain grey underneath. But that's not to say a blue colour is necessarily bad. I think the slightly blue tint of light in nearly all space shots is heavily part of the expression of the film. And so colour corrections like the one vaderious posted doesn't sit too well with me. You are removing what appears to be a conscious effort to tint the shot.
