Well, it's interesting to see that Teal and Orange filters are used just as prominently in promotional material as in the films themselves. It's a terrible trend and annoying as hell. See here for more:
Huh. I'm fairly color-blind, so I can't see the orange (or teal) tones that he's complaining about. However, I have noticed that more films lately seem to have more detail, and everything just "looks better" to me.
I've read that some amount of color-blindness is context sensitive (e.g. http://www.designmatrix.com/pl/cyberpl/cic.html); I bet that the increased contrast in these films is part of what's making them so much more visually appealing to me.
I was looking out for the Teal/Orange effect and was interested to see that it started in posters way back in the 80s already, 20 years before digital film color grading.
That's an interesting observation. I wonder if that's a more general kind of lag that can be found with other effects, with things becoming feasible in still design work some years before the analogous thing becomes feasible in film/video.
