1. I doubt I'm ever gonna get the chance to see a negative of TOS from the Paramount vaults to verify that TOS command velour photgraphed green. So I am skeptical. There are some eps, especially iirc in real sunlight on location where they come out somewhat greener. But velour is funky, with its nap. I think it depended more on lighting than on NTSC.
2. But whatever, it still bugs me that they didn't fix it early on, esp. with wraparound and dress unis being very green. The S3 polyesters come through as greener, though.
3. In the grand scheme it really doesn't bug me all that much. Be well. (OH - look at my avatar -- that's a publicity photo, not NTSC, and it looks almost brown.)
