Please don’t take this the wrong way guys, but I still have a copy of The Terminator on vhs, and it isn’t that blue. The color was always pretty neutral, except for the future scenes which are always blue (though some trailers have those scenes look very pink/magenta pushed. Probably Cameron’s floodlights to help the blue once the filters were added. Same thing for T2 trailers).
I also have a very old German dvd of Terminator that looks like it was taken from a film print (lots of print damage and cigarette burns), and it’s actually very teal, but not the same kind of teal like the blu-ray. It’s more natural, if that makes any sense.
Here’s some screencaps:
It’s the first DE/German dvd on the left. The only one with a 1.66 aspect ratio.
