How does this green light/blue light thing happen in the first place?

I think it must have something to do with them adding some color setting over the whole movie without checking for side effects. Probably the same thing as Luke's saber being green and grey shadows being blue. Just a guess of course.

I think it's alot more complicated than that, see this: http://originaltrilogy.com/forum/topic.cfm/Crushed-Blacks/post/539032/#TopicPost539032 That is just a few examples of the inconsistency that is going on with all the levels throughout the film, that's why one single setting cannot correct the damage, just from one moment to another it goes from being extremely saturated to being very desaturated, what should've been blue are green and vice versa and what should be bright is dull in another moment, I don't know if the blu-ray release have corrected some of this but that's what's going on with all the levels in the 2004 DVD, which create a wonderful mix of disaster.

I'm no expert on this, but one color setting added over the whole movie cannot be the culprit for this.

That is what my experience regrading the first film has let me to believe that as well, the colour grading is too inconsistent to use just one filter to regrade the whole thing, but if I had to choose just one filter to apply to the whole film, it would be remarkably similar to the one You_Too has created in his blu-ray regrading thread.
