Thanks, yeah, that's exactly it. I mean I can see that there's a bit of green in his skintone but so there is in that Senator screening picture and the walls are quite green there and you need to find a ballance where everything looks at least pretty much the way it should.

And I'm really happy with how this particular scene turned out, except for the skintones being too orange in the shots before Tarkin and Vader come in, which I've already fixed now.

Harmy, yeah I'm only now starting to appreciate now how this is such a delicate balancing act for you, recreating the theatrical colours. I'd never seen that picture of the screening you posted just now that has a green tint in this scene with Tarkin. You've clearly seen more theatrical sources than I have so you know that much more about what the colours should be like than I do. I don't envy you having to balance the few theatrical sources there are out there and decide what colour grading to go with, that's for sure. What i'm doing with my project is so much easier by comparison.

As You_Too says, you're doing a fantastic job here balancing the sources, recreating how it looked in the theatre and everybody here, myself included, really appreciate it. I'll try to keep my nitpicking to a minimum from now on. :)
