I'm going with the crowd and the silver. And by with the crowd I mean the market. Depending on where you come from, White, Black and some shade of grayscale are in the top color choices in most recent years.
PS. I personally own 3 red, 2 gray and one tan car.
Choosing between those 3? The Iconic Silver by a landslide. The others aren't rare in anyway shape or form. Grabber is the most common color now that anyone can get it, really lowered it's appeal to me. Infinite Blue and Iconic Silver FTW!
