I understand those are temporary colors, but I wonder if the Death Star's walls are actually supposed to share the same teal-like color.

From what I know, yes, they are. If I remember right even harmy's excellent work had that tint to the death star. It's even got a more greenish tint in some shots. I think mvertaentioned it over in the legacy thread at some point

It's definitely supposed to be there, just not so crazy green as it is in these clips. More of a blue-with-some-green-in-it.

If so, why the duel's shots look much more green than the others? It seems to me that either the presence of light makes them more blue, or the duel's shots have a different color grading. Could it be?
