I was watching the ROTJ Grindhouse, and was surprised how green some of the exterior shots of the Death Star are, especially in the early shots, and during the space battle at the end. Is this delibirate?

I ran one of the frames through my algorithm, and it came out looking a bit different.

I’m also pretty sure the small planet/moon in the background should be red, at least that’s how it appears in the home video releases, and that’s also what the algo predicts.
