It could be long and tedious... but, actually a section by section, color correction could suffice. For example, all the Tantive IV scenes, all the Reel 1 Tattooine scenes, all the Reel 2 Tattooine scenes, etc... Though, it would only be a best estimate, the color corrector would have to use his own judgment, and the colors may end up not being accurate. Maybe the simplest thing to do is push the contrast up just a tad bit, making a slightly crisper image. Still perhaps it would probably be inconsiderate to give to Adywan...
