There's an urban myth out there that holds that the color of a car affects your insurance rate. The rumor is so pervasive that some insurers mention it on their corporate websites.
It's not true. In our experience, the color of a car has nothing to do with how much you pay for auto coverage. We review auto insurance rates (among many others) here in Washington state, and we can't recall ever seeing an auto insurance rate schedule that takes color into account. Insurers do often raise rates for high performance vehicles, which may be more likely to come in red, but color itself is meaningless in determining rates.
(Here are the sorts of factors insurers take into account, including things that might surprise you -- like your credit score.)
While we're on the topic, how about the widespread belief that red cars get more speeding tickets? Snopes.com, the rumor-busting website, says that doesn't seem to be true, either:
"...It does not appear that red cars get cited for speeding more often than they statistically should."
