That Blade Runner collection is fantastic but sadly, neither the 30th Anniversary nor the 5 disc collection have the right color timing for the US theatrical (and the international cut). Those top pics are from the 5 disc which has the same video as the 30th. The theatrical had a golden hue on its release prints. Its the same as Alien, they went back to the negative and didn't color time to a release print. Instead everything was given a cool blue color timing (the Final Cut was given a green hue like Alien, which is Scott's prerogative since its his Final Cut.)

It might make a fun future project. Those pics were just a test to see what a re-timing might look like. Back to work on Alien...

I was under the impression that the "legacy" cuts of blade runner were sourced from interpositives?

edit: Turns out I had a misconception about interpositives, I thought they were already color timed, but it seems that they're merely USED to do the color timing.

"After a film is shot, the original negatives—taken directly from the camera equipment—are edited into correct sequence and printed onto fresh stock as a cohesive film, creating an interpositive print used for color timing. From the interpositive, answer prints, which include the color-corrected imagery and a properly synced sound track, are made. Once approved by the studio, the final answer print is made into an internegative used for striking copies that will be delivered to theaters for viewing."

So ya even if they scanned an interpositive, they'd stil need to color correct it properly if you want the theatrical colors.

edit2: Word of warning though, just because the laserdisc has a certain set of colors, does not mean those are correct either. Although in this case they'll most likely be more accurate than the blurays.
