Using cutting-edge laser precision, scientists have created a new color perception never seen before in nature. The color, called olo, emerged when researchers targeted a specific type of photoreceptor in the human eye, unlocking a hue that defies traditional color boundaries.
The Science Behind Olo
Our eyes perceive color through three types of cone cells—S (blue), M (green), and L (red). These cones typically respond together when exposed to any light, blending wavelengths into recognizable colors. But researchers from UC Berkeley disrupted this natural process by isolating the M cones.
A Never-Before-Seen Color
This artificially created condition allowed participants to see olo—a completely new color that doesn’t exist in typical visual experiences. Study lead James Fong and advisor Dr. Ren Ng described olo as a kind of “super teal,” but emphasized that it isn’t a mix of existing shades. It’s entirely its own category.

Expanding Human Perception
This experiment proves that our perception of color isn’t fixed. By manipulating how cones are activated, scientists can trick the brain into seeing something entirely new. The study highlights the flexibility of the human visual system and hints at untapped capabilities of the brain.
The Possibilities Ahead
While olo may not become a part of everyday palettes, it marks a powerful step toward expanding the boundaries of sensory experience. As science continues to explore how we see, the world of color may be far larger than we ever imagined.
