Actually, it is intentionally like that. I didn't colour time it to the shot of Greedo at all, I timed that shot of Han that Yoo_Too posted and left the Greedo shots to have that same timing. The thing is that there's one shot of Han that is different than the others and I tried to get it as close to the others as I could.

You Too's on the left, mine on the right. It's still far from perfect but it's the best I could do with general adjustment. Though I may yet try to redo it but only I think to match the stray shot even better to the rest:

And to me the skintone and over-all colour now appear much more natural and, what is maybe more important, film-like.
