The question is though: was the original over-saturated red as a deliberate artistic decision?
If so, then it should've been retained.
as the Blu Ray release is supposed to be the theatrical edition.
So, have we ever gotten any explanations for why the color balance was altered for the Blu Ray in the first place? Was it a choice made during the rescanning, or was it an accidental artefact of the restoration? Did they scan the negatives at 4k and simply transcribe the color tones 'as shot'?
