Neil Harbisson, a color-blind artist, believes so:
Though he himself has no emotional relationship to colors, he learned that most people do. They’re influenced by them — even if they don’t know it. "For example, if you don’t want your bike stolen, and you paint it pink, you have much less possibility that it gets stolen," Harbisson said. "If you want to avoid people jumping off a bridge, paint it green. They tested this in London, they painted a bridge green and people stopped jumping from it."
Harbisson had a tech company build him an "eyeborg," a camera that translates color frequencies into sound:
The sound is then pulsed directly into his skull, via a headband that keeps the whole thing snug on his head. "I don’t see it as a device anymore, I see it as part of my body," said Harbisson. "I started feeling this the same year I started using it, in 2004. I started to feel that the software and my brain were creating a new sense, and there was a point in which I couldn’t differentiate between what was given by the software and what came from my brain. I decided not to take it off anymore, and it’s been a part of my body since then."
