It’s interesting to note, that the 1977 bootleg recording shows a very similar color palette to the photo of the frame I have in my possession:
For comparison, here’s how that same shot looks on V2.6:
And here’s the photo of the frame you posted before:
The technicolor print frame in the photo is certainly very green like Swazzy said, turning the walls green and leaving no space for the blues.
It’ll be very interesting to see how this frame in particular looks colourwise when you get it scanned, finding out how the fleshtones look and the colour of the walls, how much blue and green are in this shot and which colour is more predominant.
