negative1 has mentioned on more than one occassion that any screengrabs that are posted here might be temporary in terms of colour timing or suffer from compression. Don't worry - I'd say he definitely knows what he's doing.
Besides, as has been mentioned several times here (and other places), the GOUT DVDs can't really be used as accurate references for colour timing. Sure, the crushed blacks (and other issues) of the '04 DVDs and the Blu-rays are over the top, but it's important to note that "Star Wars" wasn't always pretty or consistent. Check out this article for more info on that.
