Silver is a popular color... so in the future if you're going to sell the car it might make it easier.
My Corolla is "Cactus Mica" - a light greenish / blueish color... happened to be the last one on sale so I bought it... wasn't really too concerned about the color.
So far, I've noticed about 5 other Corollas with the same color as mine, after having driven about 1,000 miles - so I'd say it definitely isn't a popular color.
