Almost all of my 4wd vehicles have been white but it wasn't my choice - it's just that in most cases I bought them used and that was what was available. IMO color is about the last factor I would consider when buying a vehicle. About the only exception I would make is black - I simply don't like black vehicles, especially for something that is going to be used where it gets hot. I regard white as pretty boring, but relatively inoffensive. I did have one silver vehicle, a 1984 Mazda B2000 pickup (4x2) that was so slow I called it "The Silver Slug" (because
nobody would ever mistake it for a bullet!
)
When I drove a white 1990 Mitsubishi Montero in the mid-90's I thought it might be fun to freak out the conspiracy theorists by painting "UN" on the doors, but then again, since the thing wasn't bulletproof I decided against that.
On the one occasion that I actually got to pick my vehicle's color, the color I chose was a dark forest green, just because it's my favorite color. My current camper shell (which I bought used) is forest green, which actually looks pretty nice on my white Taco.
When I was shopping for shells, the dealers would always assure me that they would be able to perfectly color match my truck, but I knew that if I ended up buying a new camper shell, the last thing I'd want would be a color match! That would just be a little too much white for me!
BTW there was a recent news article that stated that the most common color for cars now is white.
