UC Berkeley Researchers Reveal 'Olo,' a Color Beyond Human Vision
- UC Berkeley and other researchers revealed a new color called olo on April 18, 2025, seen by five test subjects using the Oz Vision System.
- They developed Oz to selectively stimulate individual M cone cells in the retina, enabling perception beyond standard human color vision limitations.
- Participants described olo as an intensely saturated blue-green hue unlike any natural color, verified through color-matching tests and multiple validation steps.
- Ren Ng said the technique could allow people with color blindness to perceive new hues, while experts called the research an impressive technical achievement.
- The researchers suggest Oz might help study vision more precisely and eventually enable color-blind individuals to experience a fuller color spectrum.

Scientists Unveil “Olo,” a Brand-New Color Humans Have Never Seen Before
Scientists at UC Berkeley have developed a new platform called "Oz" that can simultaneously control up to 1,000 photoreceptors in the eye, offering new insights into the mechanisms of human vision and the causes of vision loss. In Frank Baum’s original novel The Wonderful Wizard of Oz, the Emeral
Scientists discover 'Olo': a new color beyond the naked human eye
A team of scientists from the University of California, Berkeley, and the University of Washington have reported the discovery of a new color, 'olo,' which cannot be seen by the naked eye. The hue, described as a deeply saturated teal, was revealed through the use of advanced laser technology. The color was made visible using a technique known as 'Oz,' a method that stimulates the photoreceptors in the human eye with laser pulses. The breakthrou…
