Black cars are known to absorb more heat than other colors, making them hotter inside. This is because black cars don't reflect light, but rather keep it inside. So if you're looking for a car that won't be too hot, you may want to avoid black vehicles. John Brauer, a Californian car owner, has four cars in his garage - two blue, two red, his son's black car (“I bought it cheaply”) and his gray convertible (a more complicated story).
Brauer put aside his own preferences to explain some of the commercial reasons why Californians own colorless cars. This is why, when you have a black car, washing it regularly, polishing, rubbing and cleaning in general is common. But if you ask these people if they really prefer black, white or silver cars on a personal level, many say “no, but everyone else does”, so they get along well. So, if you live in an area where it's moderately hot all year round, your air conditioner will have to work extra hard if you have a black vehicle.
