Changing the color of your car? Press a button

It seems to be a technology is on the way that will allow you to change the paint of your car by simply just pressing a button? Sounds great, right? The technology doesn’t sound too complex.

The variable-color paint works this way: prior to paint, the car’s body gets a special polymer coating that’s got paramagnetic iron oxide particles in it. When you press a button inside the car, current will then pass through this coating, the ferrous particles change their alignment, which alters the way they reflect light, effectively changing the car’s color. The default color when the car’s not running is white.
