One of the things I use to judge the accuracy of any color correction is R2’s blue panels. Now, they don’t come out quite the same in every scene that was shot, but in the sources I trust, they are always blue, maybe leaning to a dark cobalt. So when I see a scene that shows R2’s with a greenish tint to him, I am convinced that it has been over corrected toward the green. One thing that tends to cause corrections to lean that direction is the skin tones can turn out too red for some tastes, but I’ve found that in the reliable reference photos, the skin tones when shooting in Tunisia were a bit red. When I correct the skin tones just based on the set photography, R2 usually stays blue and the people look a bit pink, but not the magenta of the Lowry HD work. This is my color correction of the UK GOUT:

Note the lack of green in the sand crawler and Owen’s hair as well as in R2’s blue panels. I find this color pallet to be my favorite.
