How can I know the best color car to buy?

Consider three things: 1.) Dirt. If you live in a cold place, you may know that the ice melt they put down is hard on dark-colored cars. If you live somewhere dusty or rugged, dirt is hard on light-colored cars. 2.) What other people think. I know you are not supposed to care about what others think, but this is important. Here is the "normal": Red -- Fast, fury, cool; Black -- Sleek, simple, average; Blue -- Calm, unique; Grey -- Modern, cool; White -- Basic. 3.) What looks best. Think what matches your car. If a color looks silly, don't pick it.
