Yes, I think poita said that some of the IB prints had a green shift. (I'm assuming this would not be due to fading - since IB prints don't fade - it would be due to the color getting shifted in the original printing process itself.)

And again, be very careful with publicity stills - they weren't timed to match the theatrical color timing. (FWIW, the 1979 book "The Movie Brats", in a reference to the Nazi imagery of the villains, said "Tarkin lives in a gray-green world with gray-green uniforms", so what people would have seen in theaters - not just on IB prints, since those were only in the UK - has to have had at least a smidge of green in it.)

Great exercise, though - this color script is absolutely amazing.
