Introduction
For centuries, human color perception has been limited by the biology of our eyes. But today, the boundaries of this colorful spectrum have been pushed further. Scientists at the University of California, Berkeley, have discovered a hyper-saturated blue-green hue, dubbed “Olo”, using advanced laser technology. This groundbreaking discovery offers a new perspective on vision and opens exciting possibilities for future applications in science, technology, and art.
The Science of Color
Human eyes perceive color through three types of photoreceptor cells called cones, located in the retina:
- S cones: Detect short, blue wavelengths.
- M cones: Detect medium, green wavelengths.
- L cones: Detect long, red wavelengths.
When light enters the eye, it activates various combinations of these cones to form the spectrum of colors we see. Until now, the wavelengths that trigger M and L cones have been nearly identical. This overlap made it impossible for the human brain to perceive certain colors—until the arrival of Oz, a cutting-edge technology.
The Discovery of “Olo”
The discovery revolves around Oz, a laser-based system created by scientists led by Austin Roorda and Ren Ng. The technology allows precise control over individual photoreceptor cells using microdoses of laser light. By stimulating M cones more selectively than ever before, the researchers generated a previously unseen color.
The project, published in Science Advances, required years of meticulous work. The breakthrough was only possible by mapping individuals’ unique cone patterns and then stimulating up to 1,000 retinal cones simultaneously.
James Carl Fong, a co-creator of the system, describes the process as “a journey to the land of Oz, to see a color that’s beyond our natural capabilities.”
Characteristics of “Olo”
“Olo” stands apart from all other colors in its vividness. It’s described as hyper-saturated blue-green or “peacock green”—a color far beyond what nature produces. Remarkably:
- Wavelengths: “Olo” involves carefully calibrated photoreceptor activation rather than a specific wavelength of light.
- Precision: The color only appears under exact targeting. Once the stimulation is interrupted, the perception of “Olo” vanishes instantly.
- Novelty: It exceeds the saturation of monochromatic lights from laser pointers, creating a striking visual experience.
Participants in experiments described its intensity as a “wow” experience, unlike anything they had seen before.
Visual Representation
What does “Olo” look like? While the color itself exists outside the ordinary spectrum, imagine a teal or emerald-like hue turned up to maximum saturation. It’s brighter, deeper, and more vivid than the most striking natural colors. Below are simulated images (please note these are approximations, as true representations are only visible through Oz).

Implications and Applications
The discovery of “Olo” is not just a scientific curiosity. This novel color has the potential to revolutionize several fields:
- Art and Design: Artists may experiment with creating entirely new palettes, pushing the boundaries of visual experience.
- Technology: Display technologies, like VR and augmented reality, could use this to enhance immersion and realism.
- Medical Research: Oz might help study degenerative eye diseases, simulate cone loss, or even offer solutions for color blindness.
- Philosophy and Neuroscience: By introducing new sensory inputs, this research probes deeper questions about human perception and the flexibility of the brain.
Expert Opinions
Dr. Hannah Doyle, a co-lead researcher on the project, noted, “Seeing ‘Olo’ confirms that the brain can interpret completely new sensory signals. It’s a powerful reminder of how adaptable our perception is.”
Austin Roorda adds, “This discovery is just the beginning. We’re redefining how color can be created and understood.”
Personal Experiences
Five participants, including some researchers themselves, had the chance to see “Olo” during experiments. “It was like nothing else I’ve experienced,” one subject said. “The difference between ‘Olo’ and regular green is stark. It’s surreal.”
Even the researchers experiencing “Olo” for the first time described it as a deeply immersive and almost otherworldly experience.
Future Research
This discovery has paved the way for future investigations, including:
- Simulating tetrachromatic vision, enabling humans to see even more colors.
- Exploring treatments for vision loss-related conditions using precise photoreceptor stimulation.
- Developing retinal interfaces for AR/VR applications.
The possibilities are limitless, with “Olo” becoming a gateway to a broader understanding of how we see the world.
Conclusion
The discovery of “Olo” is both a scientific marvel and a testament to the power of human curiosity. It challenges our understanding of color, perception, and the brain’s remarkable capabilities. For tech enthusiasts, science buffs, and art lovers alike, “Olo” represents uncharted territory that’s bound to inspire new innovations and debates about the limits of sensory experience.
