New technology: Wild color changing “paramagnetic paint”, at the press of a button, change the colour of your car! (#2)


This is the same as the “Paramagnetic paint” video 1, but with a different vehicle (if you have watched that one scroll to the bottom of this article for the video). Well we had previously seen paintwork that could change color with water application, that was done by the change in temperature (remember those hypercolor tshirts?). Anyway, this is MUCH cooler! This changes paint colour by adjusting the voltage of an electrical current sent through the vehicle’s bodywork. We have provided two videos of this pretty wild concept.

With the introduction of a new technology using ‘paramagnetic’ paint coating, the choice won’t be set in stone the moment the car rolls off the production line. In fact, the concept is to allow owners to change the paintjob whenever they see fit – whether that be in the car park or at the lights.


The technology works by running a current through a special polymer applied to the vehicle before painting. This polymer contains particles of ‘paramagnetic’ iron oxide. With the application of an electric current, the spacing of the oxide’s crystals is adjusted, affecting their level of light reflection and thus our colour perception.


Cars, being rather conductive metal objects, are therefore the perfect medium for such a technology, with the small current maintaining a particular colour. However, with no current, such as when the car is turned off, the paint would return to its default colour of white, making finding the car after a shopping trip a tricky business indeed.
