In a groundbreaking study, scientists at the University of California, Berkeley, have unveiled a color previously unseen by the human eye, named “olo.” This discovery challenges our understanding of human color perception and opens new avenues for research in vision science.
## The Discovery of “Olo”
Researchers at UC Berkeley employed a sophisticated laser system to selectively stimulate M-cones—retinal cells sensitive to medium wavelengths of light. By isolating these cones, they induced the perception of a vibrant teal hue, distinct from any color naturally occurring in the visible spectrum. This novel color, termed “olo,” was described by participants as “profound” and “intensely saturated.” ([theatlantic.com](https://www.theatlantic.com/science/archive/2025/04/olo-color-berkeley-teal/682557/?utm_source=openai))
## Methodology Behind the Breakthrough
The experiment utilized a device called “Oz,” designed to target specific photoreceptor cells without activating others. By directing laser pulses exclusively at M-cones, researchers bypassed the typical pathways of color perception, allowing subjects to experience “olo.” This method underscores the complexity of the human visual system and its potential for untapped perceptual experiences.

## Implications for Vision Science
This discovery has significant implications for our understanding of color perception. It suggests that the human eye and brain can perceive colors beyond the traditional visible spectrum under specific conditions. This could lead to advancements in treating color vision deficiencies and enhancing visual technologies. However, some experts, like John Barbur from King’s College London, question whether “olo” is genuinely a new color or an intensified version of existing hues.

## Real-World Applications and Case Studies
The discovery of “olo” parallels previous accidental findings in color science. In 2009, chemist Mas Subramanian and his team at Oregon State University stumbled upon YInMn Blue, the first new blue pigment in over two centuries. This pigment has since been commercialized and incorporated into various products, including a Crayola crayon.

Similarly, the identification of “olo” could inspire innovations in art, design, and technology. By expanding the palette of perceivable colors, artists and designers may explore new creative possibilities. Moreover, understanding how to induce the perception of new colors could lead to advancements in display technologies and virtual reality, offering more immersive experiences.
## Conclusion
The unveiling of “olo” marks a significant milestone in vision science, challenging existing paradigms of color perception. As research progresses, this discovery may lead to practical applications that enhance our visual experiences and address color vision deficiencies.
**Call to Action:** Stay informed about developments in vision science and consider how emerging discoveries like “olo” could impact various fields, from art to technology.
