When Neil Harbisson was a kid, he could only see in black and white.
In fact, he wasn’t totally convinced that colours actually existed.
But now, Harbisson can sense colour.
He still can’t see colours. But now he can hear them with a device he helped create in 2004 called the Eyeborg.
The device can detect 360 colours the human eye can normally perceive. It also detects infrared light.
