It is very hard to reach a "perfect" result without taking out each element in each frame and change the colors separately, so naturally, no matter what I do with this it won't look completely perfect.
I understand your point though, and I'm trying to make it as balanced as possible and to recover as much color as possible without oversaturating it. I won't go for the look of the JSC though since in my opinion there's either too much yellow or too much green overall.
The biggest problem right now, is that when using vibrance to dig up some desaturated colors, some scenes are affected in a bad way since the movie is very inconsistent with colors. Here's that rebel soldier closeup using my current script:
It's one of those shots that come out with a bit stronger colors.
