Which are the correct colors? Who knows!
From this post the producer of The Thing, Stuart Cohen, wrote:
My own anecdotal belief, based on days spent in timing sessions and checking print runs, is that the Scream transfer is much more faithful to our original intent. The idea was to drain as much color from the film as possible - not only to give it that grey-blue COLD look - but in order to provide a platform for Robs stuff to explode on screen in all its Technicolor glory…
I also saw a screening of the film last year after getting the spoRV release and thought the film’s colors were more blue. On my calibrated TV, the spoRV is actually a bit too red in some spots in the snow. I am waiting for the new BD to arrive, so I can’t comment on how it compares to the film screening that I attended.
The first non-anamorphic DVD had the uncensored commentary. The subsequent releases were edited.
My opinion is that using the new BD with the old DVD uncensored commentary and standalone soundtrack is the way to go. However, this isn’t my project.
