At this point it does seem the color of technicolor prints (I’m pretty sure the 1977 bootleg is also of a technicolor print) does have a green shift when projected as has been argued by many, and any color grading attempting to match these colors should incorporate these anomalies. However, it’s also interesting to estimate what the colors would look like without these anomalies. One thing which helps in this case, is the presence of subtitles, which are supposed to be white, and can thus be used to balance the colors.

That is about what I came up with for that shot. Then the shot of Leia and R2 remains green, but is less green. I think the green is integral to the 77 print, but it should be minimized as much as the surrounding scenes will allow. I think to accurately represent the 35 mm prints, we need to take the reported green tint of the Tech IB and compensate for it. So this is the color grading I would champion.
