Here it is compared to Harmy's (which has a blue cast)...
Poita (sub-par uncorrected Tech):
Harmy 2.5:
The sabre is corrected from green to blue (as it is on the blu-ray, which I forgot about), but not the training orb back to grey/green. Chewy's colour certainly looks more natural from the print as well. As point pointed out below, this capture was from a "sub-par print" and was not colour corrected.
However, look how much closer to that print Harmy's looks than the other versions! What a testament to the correction he did to the film.
