Unveiling Olo — A Color Out of Oz!

"Olo" does not exist in nature, nor can it be found among paint cans. But for a very select few, olo can be seen — through the intervention of careful computing and lasers. A team led by vision scientist Austin Roorda and computer scientist Ren Ng at UC Berkeley figured out a method for stimulating only one specific subset of cones of the retina. It's the only way to view this spectacular teal. Creating the color is helping push the boundaries of vision science. Follow Short Wave on Spotify, and Apple Podcasts.
