Many cars in advertisements, exhibits and at car dealerships in the United States are red, blue or green -- but almost 75 percent of new cars sold in the United States are black, white, silver or gray. Les Jackson is a reporter who writes about cars. He says the car colors Americans choose do not show dirt as much as the colors of other cars. He says that means the owners wash their cars less, saving money. And he notes some areas that are suffering from water shortages do not permit people to wash their cars often, if at all. Dan Benton works for a company called Axalta, which makes supplies for international carmakers. He says when white cars are sold by their owners, they often sell for higher amounts than cars of other colors. And he notes that white cars “absorb less energy” than cars of other colors.
