OLO

"Olo" is a newly discovered color that lies beyond the typical range of human vision. Unveiled in 2025 by researchers at UC Berkeley, it was perceived by only a handful of individuals through a specialized device called "Oz" .

What Is Olo?

Olo is described as a profoundly saturated blue-green or teal hue, more intense than any color naturally occurring in the world. Participants who experienced it noted its unparalleled saturation, making even the most vivid natural colors appear muted in comparison . (Scientists hijacked the human eye to get it to see a brand-new color. It's called 'olo.')

How Was It Created?

The color was perceived by using the Oz system, which employs lasers to stimulate only the medium-wavelength (M) cone cells in the retina, responsible for green light sensitivity. This selective stimulation bypasses the usual overlapping responses of the eye's cone cells, allowing the brain to perceive a color not typically seen in natural vision .

Can Olo Be Reproduced?

Currently, olo cannot be replicated through conventional means like screens or paints. However, British artist Stuart Semple has attempted to recreate it in pigment form, naming his version "Yolo." While it's inspired by the concept of olo, experts note that true replication is impossible due to the unique way olo is perceived .

Why Does It Matter?

The discovery of olo opens new avenues in understanding human color perception and the functioning of the visual system. It could have implications for studying color vision deficiencies and exploring the limits of human sensory experience .
