“It couldn’t have been me your honor, my car is red!”

One of the hardest decisions when picking a new car is choosing the right color but the day when cars will be available in multiple colors could be here sooner than you think. Scientists have developed a new coating called ‘paramagnetic’ paint that has the ability to change colors at the touch of a button. One carmaker looking into the technology is Nissan, which has already developed a self-healing paint.

Before the vehicle is painted, a special polymer containing the special ‘paramagnetic’ iron oxide particles is applied to the car’s body. An applied electric current then adjusts the spacing of small crystals within the iron oxide particles and therefore affects their ability to reflect light and change color.
