There are a couple Universal Studios Japan camcordings, they look more blue. The Hollywood ones, I can't tell. It may be that the film was retimed and reprinted for Florida only, but that the old prints as projected showed both blue and teal? I dunno. I know it's not DCP because people on theme park boards are saying it's not digital yet (but that they got a new print at some point?)

Based on the existing evidence, I am of the opinion that when Cameron's stuff was originally timed for theatrical projection, it had more teal than we like to assume, but that the trademark blues were still there. It could be that due to limited color space, camcordings of any kind will pull out either the blues or the teals more than the other? I remember the film having that light-blue/teal look, but I'm going off memories from 1997. I can't truly remember the colors.

I'll have to put in links to the other camcordings.
