Harmy, I am not suggesting that each archival version should have different colors. I am suggesting that Bladerunner had an original color timing. I do not think the 1997 DC DVD was trying to establish a different look for that particular version: I think it just transferred the film, with the DC changes, but ended up with too red a color palette. In short, I think there is an original color timing, reproduced with varying degress of success on the various releases, and a new color timing for the FC, nothing in between.
There were also fixes in the FC that were not on the archival releases, so it is not the same transfer.
