Please don’t interpret my post as disparaging your abilities, that was not the intention. Yours is still much better than the Blu-ray, it’s just this one shot I thought was a little greener than usual. The photo you just posted looks just a tad less green to me too. But, I suppose I’m just used to the more neutral colors in the home releases, as you previously mentioned.
I didn’t take it as criticism. It’s just one of those weird things in the Technicolor prints. Here’s another shot that from that scene:
Here you can clearly see, that while the foreground is very green, the background and R2-D2 are fairly neutral, which makes it seem as though the scene was lit with a green light.
