Oke, here we go. Here are four frames of different scenes in close proximity of the raw scan of the LPP used to create the SSE. For those that don’t know this, this is not a technicolor print:

Now, even for the raw scan, that is clearly blue shifted, it is pretty obvious, that the Leia/R2 corridor scene is green. However to make things more clear, I balance the Darth Vader shot (no match to the technicolor print), such that the stormtroopers, and the walls are white, and Darth Vader black (remember Mike Verta maintains the walls are slightly mint colored, so I’m actually overcompensating for any green shifts):

Now I use the color balancing LUT to correct the other frames:

I rest my case. Delibirate or not, the Leia/R2 corridor scene was definitely green for 1977 prints, technicolor or otherwise.
