Change the Colour of Your Car by Pressing a Button

Scientists have developed a new coating for cars 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.

The process is perfect for metal objects like cars because a continuous small current is needed to maintain the desired color. When the vehicle is switched off, the car returns to a default color of white.

The coating has the ability to reproduce any color visible to the human eye and it takes less than a second to change the entire car. The first commercial applications could be on the market as early as 2010.
