Much thanks for all the input. Contrary to comments that asking for color advice is not helpful I would disagree. Many have given bits of info that are helpful. No they are not definitive but it helps to get other's perspective. For better or worse I am starting to stray from blue now as a result.
As far as seeing the colors in person, I think I have seen every color in person. I have been to the MD service center multiple times and taken many photos of different cars. I have been to the Tysons and DC stores many many times, the NY store, and I have toured the Tesla factory in Freemont.
The first car I saw that made me awe struck was a blue with grey 21s and spoiler. I still like that color combination a lot, possibly the best, but I plan to go with the 19s. Plus there is a lot of input about difficult long term care of blue, and I worry about that. So right now I really have no idea. Red looks great, but I fear the lust will fade. Pearl is nice, but not sure about the 19s. Now I am looking at gray but I worry it is a fad color. I wish I liked black. Black is my car color of choice on most, but it does not seem flattering on the Model S.
As the title says, Color indecision!
