If one watches the blue screen BTS footage from Empire of Dreams or From Star Wars To Jedi, you will see that the Falcon is generally a dingy white.
And like I've said before, there's no sense in you damaging your health to get this done sooner than later. As I say while working on my films, no one should have to get hurt in order to finish the movie. I know it's not easy pulling yourself away from the work once you get started, but probably best to limit how much time you put in every day (or week). Basically, just relax more, or take an hour nap during the day. I hope things turn around before too long, Ady.
