I disagree about these scans being a good reference - we don’t know how they were scanned or how the pics may have been manipulated, but mainly, we’ve seen quite a few prints by now and this is the only one that stands out as this radically different - I think it’s just a print that’s beginning to fade and thus has a red bias.
Even the GOUT and other old home video releases clearly show the walls as green/blue when saturation is boosted - remember the time when we took the GOUT as the best reference and everyone was correcting the Death Star walls to be grey and then we saw those Senator screening photos and someone tried boosting the GOUT saturation and those same kind of colors started coming out - it was a revelation. And sure, we may have gone a bit crazy in the hunt for the Technicolor look for a while, but that was because that’s how much of a revelation that was, and now we know better than to trust one reference beyond all others and we know to use moderation and our best judgement when doing the color grading but I’d hate to see us go back too far.
