I think you really should have a look at the Technidisc transfer that’s available at the anatomical location. It is pretty much what you are after, that is, a saturated color version of the GOUT.
No, that’s not what I’m after. Saturation levels are still up for debate. I’m interested in reproducing the technicolor print colors, and creating a color reference for that purpose. The colors of the Technidisc are closer, but not really representative of the technicolor print colors. Also, the color balance of the earlier transfers is all over the place, and the R2 canyon scenes have been altered.
The hypothesis for this regrade is, that the colors of the GOUT, while not accurate were globally corrected. As such, they contain the color relationships of the original interpositive. As a consequence you can retrieve the entire technicolor print color timing to a good degree of accuracy, by matching a few key shots to technicolor print references with the color matching tool. My main color reference here is the Obi-Wan/Luke shot, which Mike Verta has confirmed is 98% accurate in terms of hues of a projected technicolor print, and to a lesser degree his Leia on Tantive IV color grading, and the 70mm shot of Tarkin in the Death Star conference room. The rest of the colors pretty much just come out automatically. For example the yellowish/green color in the trash compactor scene, which is seen in all technicolor print scans, is a result of this methodology, as are the blue walls of the Death Star interior, which Mike Verta maintains is how they should look.
