I had a similar dilemma regarding the sport AB and the full size. I ended up choosing the RR SC for several reasons but your right it is only about $10k more fully loaded as long as your dealer is not marking it up. Mine isn't. The wait is the same for the RRS AB and the RR SC so no big deal.
Since you already have a sport I say go for the full size. I can't help you on the color thing. I like lighter colors on my exteriors. Good luck either way!
