Is a white car cooler than a black car?
Besides, is a black car really hotter than a white car?
After all, it's generally accepted that black cars are hotter in the sun and white cars keep cooler in the summer, but is it really true? The black car's cabin measured a scorching 130 degrees Fahrenheit, while the white car's interior registered only 113 degrees.
Secondly, does black interior make a car hotter?
Surface temperatures on black upholstery will still be measurably hotter under the same conditions, but using a reflective windshield blocker or solar ventilation system will have a much more dramatic effect on temperature than choosing a lighter interior color.
It has to do with reflection. White and other cool colors, such as light blues and silvers, are better at reflecting wavelengths of light, or heat. If you had a white and black car side by side on a sunny day, and measured the interior temperatures, the white car would be cooler, but only by a few degrees.
