I personally think that the darkish yellowy reddish brown in the clip I posted up looks fairly accurate to the lighting one would find in a bar like that with very few windows letting in natural light (the one we can see behind greedo is pretty far away), dark, smoke-filled and murky. I think it works because it makes the cantina seem more dark and dangerous, with shifty fellows hiding in the shadows. I think viewers are meant to be uncomfortable with the seemingly dark and sinister surroundings, much like Luke is himself, having had a sheltered upbringing and never been in place like that frequented by criminals and others of a less than savory nature. It's similar in my mind to when the the hobbits enter the prancing pony in FOTR and are totally out of their element in a murky, smokefilled inn and very strange people all around them.

Everybody has their preferences in colouring of course. Still, i'd be careful not to start changing the colour scheme too much to your personal liking. That's a slippery slope if ever there was one. The film could very quickly become unrecognisable IMHO.

If you don't mind me asking Harmy, what source/s are you using as a reference for what the colour grading 'should' be?
