I could try to make a LUT, if needed. If you provide a corresponding set of frames from the two versions (BD vs preferred color) from a variety of scenes I could try to find a grade that works on the whole film.

If it turns out that the color difference between the two versions is about the same from scene to scene I imagine that the result could be good. If not, there might need to be a set of different LUTs for different types of scenes.

One thing I’d like to try is to take the image sets and lay out the frames from each version in a grid that represents a version of the whole film, and then try to match the BD grid to the target grid. I imagine that could be helpful when trying to adjust the whole film at once.

The color grading/correction solution that I use does have a color match tool. The matching is not as advanced as Dre’s, but I think it could at least give me a decent starting point for further tweaking.
