If you have ever been indecisive about what color car to buy, BMW may be able to help. At the Consumer Electronics Show in Las Vegas in 2022, the German automaker showed off its new color-changing paint technology, which is more similar to the one used in the Kindle than you might think.

The color-changing paint technology used in e-readers and the old Pebble watch is making its debut on a concept version of the BMW iX.

The surface coating of the BMW iX Flow features many millions of microcapsules with a diameter equivalent to the thickness of a human hair. The microcapsules contain negatively charged white and positively charged black pigments. Depending on the setting, stimulation by means of an electrical field causes either the white or the black to collect at the surface of the microcapsule, giving the car body the desired shade.

BMW says that this is just an advanced research and design project, and that it won't be seen at your local dealership anytime soon.

The paint scheme can be triggered by a button. The colors are limited to white, black, and grey. BMW says it could have implications for the efficiency of its electric vehicles.

The company says a white surface reflects more sunlight than a black one. Changing the exterior to a light color can help reduce the heating of the vehicle and passenger compartment. The vehicle will absorb more warmth from the sun in cooler weather.

The concept of personalization is very popular in the auto industry. BMW is bringing the concept of personalization to the exterior of the vehicle, while most of the efforts are focused on the interior.

It is not known whether this high-tech paint can survive extreme weather. I don't think this would handle well in a hail storm. Don't listen to me. The car is color-changing.
