I’m sure it’s been mentioned before, but for some reason I’d always thought that the purplish cast in the 04/11SE was just somebody getting a wild hair that the colors should look totally dreadful and nobody speaking up to say maybe they shouldn’t. The video linked below, to me, indicates that the purplish cast may have been an attempt to re-create the colors of the “THX” home video releases, rather than theatrical colors like the 97SE.

Maybe this isn’t news to anyone else here. But apparently purple faces have been with us for a long time, not that this makes them look any better. Also, the Japanese Special Collection had pretty good colors, but that’s not a surprise to anyone.
