The North Carolina School of the Arts Film Archive has a technicolor print of Star Wars, part of Ray Regis’ collection (https://greensboro.com/a-reel-jewel-school-of-the-arts-archive-is-one-of-the-best/article_1a78fe79-c018-59aa-8010-e4d941974d6d.html), and I am pretty sure parts of it has been scanned for various restoration projects. I watched it 4 or 5 times while I was there, and it was pristine and just a joy to see because it looked pretty much exactly the way it had when I saw it originally in 1977. When I first saw the print in 1994, it was incredible. Then when the re-release came out a few years later and we went to see that in the theater, we were amazed at how much better the Technicolor print looked then the new THX versions or whatever they had just put out were.

When Star Wars was released in the UK, they realized they needed some extra prints because of the popularity of the film, and since everyone else was busy, they had Technicolor make strike like 12 or 13 prints. Although no one really shot on Technicolor anymore, they still used the same process to create their prints. Somehow Ray got ahold of one, and I know for years fought with Lucas over it. He also had Technicolor prints of Jaws and a few other movies.
