From the beginning I have been working with the GOUT. Not as the best source of color, but as the best testbed for global color corrections. I have the 1 fps sample that Mike Verta shared of the Tech IB scan. It suffers from a lot of color issues at either end. When I balanced it and then worked on making the GOUT match it, I got pretty much what you have gotten. Just less green in the darker areas and less yellow in the brighter areas. I think what I got could be called a mint green for the Tantive IV walls. And that shot of Leia and R2 in the corridor has that distinctive green tint, just not as strong as what you are getting.

One of my operating theories is that the interpositives used for Eps 4, 5, and 6 from 85 to 94 were all scanned with the same settings to yield the GOUT versions we have (except for the opening crawl of Ep 4 which came from some other source). When I applied those same settings to Ep 5 and compared it to the test scan and initial color correction Poita has been working on for TESB, the colors matched very close. I have not tested it with the grindhouse ROTJ yet.
