In order to see it, researchers must map an individual retina, classify every cone, and use lasers to activate only the M-cones. This feat was first achieved on April 18, 2025, at UC Berkeley with five participants. Professor Ren Ng called olo “more saturated than any color you can see in the real world.” Participants described it as an unprecedentedly saturated blue-green and found ordinary colors dull
