Every transfer of the movie has different color timing. Both the Sony transfer used for the 20th Anniversary DVD and the Metrodome transfer used on the UK and Australian BDs have decent color but neither one matches and both show signs that the colors may still be wrong. It seems like ever since the Rhino DVD, they've been making more and more of an effort to oversaturate the colors as well. I'm not sure f it is simply a desire to try and make every video release look more vivid than the previous one or something wrong with the negatives they've been using.

(edit: I found out that the UK releases used a new transfer off of the original negatives.)
