Getting the colars right in low/odd lighting situations would require looking at the various pre-SE releases and bootlegs. Because in the real world, the lighting in a bar would make colors "incorrect". In the presence of candle lighting, my eyes - everything for that matter - might indeed look red. That is, correcting every scene to make the colors "right", might in some cases actually be wrong.

Also, just to be certain, has it been ascertained that Han's boots are black, and not dark leather?
