OK, so does this mean the Technidisc/GOUT IP retained its color into the 90s? How does that explain the somewhat desaturated and neutral look of the GOUT?

My original assumption was that either the source element wasn't fully timed, or that it was done in telecine to compensate for fade. The 1983 Spanish-dubbed LPP print and the 1989 French widescreen laserdisc seem to come from a source that had the same variations as the GOUT, and both have certain scenes with pinkish or bluish casts (the French LD is worse, I had assumed it had been due to another 6 years of fading on the source element).

The 70mm cells show the gold cast on Tatooine, the green-blue tinge to the Death Star interiors, and so forth - quite close to the IB Technicolor (including another IB print which made its way into the hands of a British film-cutter, who has been selling it piece by piece on eBay UK). And as I said, the blowup that was chopped up to make the cells was printed on 1995 stock.

So was the GOUT neutralized in telecine even though it came from a fully timed IP? The Technidisc does seem to have more of the original color timing in evidence, but even that isn't perfect. I don't know what to believe anymore...
