I realize this issue has largely been put to bed and I’m not trying to start any new arguments about it - I think we’ve all agreed that the shot is supposed to be at least a little green, but I was flicking through my UK souvenir program of Star Wars and spotted this, so I scanned it in:
Obviously not a reliable color reference for many reasons, but interesting because I’ve never seen the Leia and R2 shot look so green anywhere else.
