The eventual settling on teal and orange is interesting. I'm curious what the feedback loop was that told the marketing department "this is what will make more money". It seems such a subtle thing, and I would think red (as an alarming color) or green (as the color we see best) would end up figuring more prominently.
I'm sure you've seen this[1] before, but the answer is probably more of a feedback loop. The big-money movies could afford to do more color alterations that caused movies to appear to "pop", getting audiences used to those colors, forcing less-expensive movies to do the same as the technology to do so became cheaper.
