So here's my thing on the paint. I see two options:
1) Use the black base with light blue. This means the light blue stays on the headlights, the big stripe on the side, etc. (Not sure about the halftones). The main changing color would be the striping (which for the most part on the current theme is orange.
2) Use two different paints and try and keep teams to one or the other. This would mean 1-2 teams use the blacks, 1-2 teams use the whites.
I've had a lot of people tell me the whites are really nice, and I must say, I really really like it, too.
