Weird, I always thought those pictures looked greenish too, but if you think they don't...

I know the Senator print had color differences from the IB print(s) the reference stills come from - the shots in the light saber duel of Ben and Vader in front of the big doorway looking out toward the Falcon had an overpowering blue tint, but there is a picture of the same scene from the Senator and the colors looked more "normal".

This is most likely due to the automatic white balance on the camera taking the photos of the screen.
