It looks like Gary Tooze at dvdbeaver started the ball rolling when he said (about Desk Set) "The new 1080P is characterized by its very blue-teal hue. It appears to even affect the pastels (clothing) although the colors are quite tight."
Which prompted someone to send in the following:
NOTE: BK says to us in email: "I don't know when it became fashionable to overuse the term "teal" in terms of Blu-ray transfers and to apply that term as a negative, when Desk Set finally looks exactly as it should - it has no teal/blue leaning to it at all - it's just right for the first time - the middle shots are green - you can't think the film ever looked like that - and the color on this Blu-ray is a perfect replication of what this film looks like in dye transfer Technicolor - I owned a print of it and it's exactly the same. And the same goes for The Black Swan, which also replicates perfectly now what it should have always looked like." (Thanks BK!)
It's always hard for me to judge color accuracy on older color films, I have no frame of reference. Personally, I'll end up getting The Black Swan. If it's a classic swashbuckler on blu-ray, I'll own it.
