The SW 70mm frames are not pink though. The probably have faded a bit, but the source is different. Probably some sort of dupe, which therefore has had less time to fade, while the Jedi frames are based on the original-release master of some kind. Prints fade at different rate depending on how tthey are stored, but SW vs Jedi is pretty extreme difference.

Anyway, yeah, they aren't a pristine reference for colour, but they aren't totally useless either.

Bkev: as far as I can tell, the DS interiors are supposed to be a greenish hue much of the time. How else could you explain a "pristine" print that has totally screwed up wall hues while having normal looking skin tones and white balance? And which also happens to correspond with caps of the Technicolor fade-free print, as well as other sources...

The notion that the DS interiors were always neutral grey appears to be highly erroneous.
