About the color thing and old movies:

Check this comparison I made from ESB.

First pic is a scan of an original print. Second is raw GOUT. Third is our version.

Notice how pink/magenta tinted the original scan is, with unnatural skin tones, but also how colorful it is. Anyway, all three movies have a kind of similar tint in the GOUT, so we ended up balancing the colors in the same way in all three movies. See how much more natural that shot looks now. And the colors look just as strong as in that print.
