Let your mood control the colour of your car

French car manufacturer Peugeot has unveiled a new car that uses an innovative reactive paint to change its body colour in order to reflect its owner's emotions, be it happy, sad or anything in between. The driver's moods are detected via heat sensors integrated into the steering wheel, which read their body temperature and pulse rate to change the exterior colour of the car accordingly, say the engineers.

This pioneering new technology has been developed by Engineers in UK who used a psychochromatic coating or mood paint, which alters the molecular structure of the paint to emit light at varying wavelengths.

"Our customers can experience this innovation behind the wheel of the RCZ -- a sports coupe that already inspires goose-bumps with its double-bubble roof line," Vince Clisham, the product manager at Peugeot, said in a media release.
