The 1985 CAV P&S LD of The Empire Strikes Back might be a good color reference.

I know that the 1985 CAV P&S LD of A New Hope has surprisingly-accurate colors, as it was pressed from a 1982 master.

Would it be possible to see some screencaps of both? i.e. using the Star Wars caps, we could see if there's any global problems to that master/transfer (such as desaturation, weak yellows, poor contrast, etc) because we have such good references there. Then we could look at the Empire screencaps and see if it could possibly be that we could apply the same global fixes there. Just a thought.
