In fact, he wasn't totally convinced that colors actually existed.But now, Harbisson can sense color.

He still can't see colors. But now he can hear them with a device he helped create in 2004 called the Eyeborg.

The device can detect 360 colors the human eye can normally perceive. It also detects infrared light.

"Hearing colors changes the way you see everything," Harbisson says in a Cyborg Foundation video.

Harbisson says he finds the sounds generated by colors in supermarkets "stimulating."

He also turns music, like Justin Bieber's "Baby," for example, into vibrant paintings—translating the sounds of the song back into the colors he's learned to associate with them.
