I have been working for 3 years to figure out how to correct ANH from the Blu-ray and I only hit on the solution a couple of months ago. They need more yellow. Not a shift in the hue, but an added hue. There is not enough yellow while there is plenty of red. The results for both the skin tones and the rocks (at least in this sequence) is that both should be peachy/orangy. Trying to make it either red or yellow can only be done by removing color that is supposed to be there. You have to balance it. I’ve bugged DrDre about this before and his has refined his tools to come closest to the original colors as he can. I think some of the shots need a touch more yellow, but definitely no desaturation or removing other colors. Definitely not a shift to the yellow or anything.
And you have to look at skin tones, costume colors (especially compared to how the costume appears in controlled lighting), set lighting, set colors (mostly lost but in the case of natural features we can go visit them and photograph them with modern cameras and see them with our own eyes), etc. Some of my scene corrections in TESB are almost imperceptible while others really stand out. You have to make final corrections with a light hand. I have learned this from being far too heavy handed myself. I’ve had to undo a great many corrections because they went too far the other way.
