Scientists hijacked the human eye to get it to see a brand-new color. It's called 'olo.'

“With this technique, the researchers enabled five people to see a new color, dubbed “olo,” which the study participants described as a “blue-green of unprecedented saturation.””

Berkeley researchers fired lasers at individual cone cells and five people saw a color no screen can show. Some of the five were the researchers themselves. It is a lab tool for studying vision. Nobody is selling an olo display.
