It could very well be that I'm just used to the original desaturated look of Star Wars, accurate colours or not. Seeing it 100+ times as a child on VHS (which, in turn, was taped from TV) is certainly causing me to be biased, and probably not in a good way. Maybe the colours I'm used to seeing are bad, and the tweaks are good... I don't know, hence why I just wanted to get everyone's input one last time. But I just can't help thinking of Star Wars as a bit brighter, visually-speaking.
Honestly, if I'm alone in thinking the "as is" GOUT colours are better, then you really should trust in the majority's opinion/your gut DJ. Maybe my eyes are just shot :) Plus, as you said, you'll never please everyone, and I'm sure you'd like to put this project to rest before you're old and grey.
Regardless of whether you go with the tweaks or not, I'm sure this is going to look fantastic when you're done.
