I had color grading done on a project. I'm now wondering if the color grader actually did just a luts instead of really color grading the footage? in this shot her hair looks green
Taking a quick look at the tonal ranges in the scene. A lot of the vegetation seems to fall in the same tonal range as the hair. Looks like whatever was applied to the overall grade in that tonal range has affected her hair. As has been pointed out, need an unedited frame. Maybe it was a LUT. Could still be avoided, though.
Not knowing what you are after for the final "look". Though it looks like you are after a pretty dystopian desaturated bleak scene. I think you'll find the 'green hair' shot has an overall green bias across the whole shot. Just look at the green bias in the highlights of the sandy salt pan looking piece of ground on the left-hand margins. Very hard to work from low res JPGs but having a guess at what you are after, I would have pushed the scene something like the bottom shot in this comp. Keeping the green out of the hair, of course. It was pulled from your 'raw' image.
I'm wondering the guy I hired to color grade the film only did it as a luts but charged me as color grading? This film was shot on the Red Epic Dragon 6k (R3D) Codec
