I don't think so. It would of course give you a definitive idea of what the colours on set really were, but SW was shot with a variety of filters, lit specifcally, and, as has been pointed out, intentionally graded after the thing was assembled.

Maybe not. Back in 1976, movies put as much as they could in front of the camera lens. Their post-production "grading" was nothing like today's (where everyone does it and much of it is done wrong). And Lucas wasn't 20 years older with allot of time on his hands to toy with it:

"... George recalls. 'I really just wanted to get done with the damn movie and I didn't care what it turned out to be.' " -p.176, Skywalking: The Life And Films Of George Lucas, by Dale Pollock

Yeah I know this is a week late, but wow that's really nice. AFAICT it's mostly desaturating the orange and leaving the rest about the same. I wonder what this process would do to 3PO though.

It was a 50-50 blend for this frame. Others may look better more one way or the other. And still others may look fine untouched. This was just a way to quickly exemplify for Harmy my observations ("too orange" is too obtuse).
