Obviously anything pre-2001. Isn’t the color timing pretty good in the official VHS? At least I remember it looking more appealing than the DVD. Then there’s the legendary “Z” bootleg that I even own on VHS. That one would definitely have the right color timing but the lighting of the movie theater messes everything up + the quality overall is pretty bad.
I don’t know how familiar you are with RU.08’s attempt at recreating the theatrical version but I’m going to link the thread here anyway: http://originaltrilogy.com/topic/TPM-1080p-Theatrical-Preservation/id/17311
^ Really good information here!
Maybe you could find something useful regarding the colors…
I have downloaded the Z VCD from myspleen to use as a reference for the next run, and I created a quick album of shots from my Collectors VHS set for comparison to the other albums: http://imgur.com/a/ddnI9
Here is a quick comparison of the kk650 and 1080p for about 3 and a half minutes in: http://screenshotcomparison.com/comparison/212747
You can see kk650 has a strong teal tint through the window, and Naboo looks very bright and soft (the white atmosphere is teal here), compared to 1080DVD.

I also just won an auction for a 35mm Film Reel of TPM Trailer A, so hopefully this could help us!
