BERKELEY, Calif. – In a groundbreaking study, researchers at the University of California, Berkeley, and the University of Washington have identified a new color, dubbed “Olo,” that exists outside the range of human color perception under normal circumstances. Only a handful of individuals were able to perceive this unique hue during a specialized experiment.
Unlocking a New shade: The Science Behind “Olo”
The findings, published in Science advances, are hailed by some experts as a significant leap forward in understanding color perception. The research team employed a novel technique to selectively stimulate light-sensitive cells, known as cones, within the retina. This method allowed them to isolate and activate the cones responsible for green color perception.
“Olo” cannot be replicated on standard display screens, nor is it visible in the outside world through conventional means. Only those who participated directly in the experiment experienced this new color firsthand. Ren Ng, an electrical engineer and co-author of the study, described “Olo” to The Guardian as “incredibly saturated” and possessing an “unprecedented intensity.”
Why Can’t We See “olo” Naturally?
The color “Olo” exists beyond the typical spectrum of colors that humans can perceive. Understanding why requires a basic understanding of color perception. Cones in the retina capture light and transmit signals to the brain, but they are configured to respond to a specific range of light wavelengths.
Under normal conditions, the overlapping functions of these cones prevent the perception of colors outside this range. For instance, cones primarily sensitive to green also respond, albeit to a lesser extent, to red and blue light. This overlap limits our ability to see colors beyond the standard spectrum.
The breakthrough with “Olo” came from selectively stimulating the M cones (those responsible for green perception), triggering a entirely novel visual experience. This was achieved using advanced technology that could isolate and activate these cones without interference from other types.

Researchers have likened “Olo” to a more intense version of green water, a hue not found within the conventional visible spectrum. While participants in the experiment could perceive it, reproducing it outside the laboratory remains impossible, limiting its immediate accessibility.
Diverging Expert Opinions
The discovery has sparked debate within the scientific community. John Damaged, a vision researcher at the University of London, told Smithsonian Mag that he believes “Olo” is not a new color, but rather “a more saturated green” experienced under specific visual system conditions, limiting its practical application. Conversely, Manuel Spitschan, of the Max Planck Institute of biological cybernetics, lauded the experiment’s technical sophistication, calling it “a revolutionary advance in the understanding of the mechanisms of color vision.”
The Discovery Process: how “Olo” Was Perceived
The “Olo” discovery stemmed from an experiment led by engineer ren Ng at the University of California, Berkeley. Using a laser device called ”Oz,” researchers stimulated the M cones in the retina, creating the visual sensation of a new color.
The technology employed was precise enough to deliver micro-doses of laser light to individual photoreceptor cells in the retina, activating only the targeted cones. This precision was achieved through sweeping ophthalmoscopy with adaptive optics (Aoslo), which mapped the participants’ retinas and allowed for precise light direction.
The initial perception of “Olo” occurred when participants received these laser pulses in a specific retinal area. Upon M cone stimulation, volunteers described a greenish-blue tone, more saturated than any previously known color.
Confirming the Novelty of “Olo”
To validate the experience, researchers conducted a color comparison test. Participants viewed “Olo” alongside an adjustable color and attempted to match the tones. The closest match was green water, but “Olo” remained more intense. Participants needed to add white light to the reference color to approximate “Olo,” further suggesting its distinct nature.
While ”olo” remains confined to the laboratory, scientists suggest that OZ technology holds promise for broader applications. Some researchers believe it could potentially aid individuals with colorblindness (Daltonism) in perceiving colors more accurately.
olo: Unveiling a New Color Beyond Human Perception
scientists at the University of California, Berkeley, and the University of Washington have made a remarkable finding: a new color, “Olo,” that exists outside the typical range of human color perception. This groundbreaking research challenges our understanding of how we see the world. Let’s explore this engaging topic.
What is the color “Olo”?
The color “Olo” is a newly identified hue that humans can perceive under very specific experimental conditions. It is described as an “incredibly saturated” greenish-blue tone, more intense then any color previously known.
Where Did the Name “olo” Come From?
The provided text doesn’t detail the origins of the name “Olo.” Though, it’s likely a designation chosen by the research team to identify the unique color they discovered.
Can We See “Olo” in the Real world?
No. “Olo” cannot be seen in the natural world or reproduced on standard display screens. Its perception is limited to those who participated in a specialized laboratory experiment.
why Can’t We See “Olo” Naturally? The Science of Color Perception
Understanding why “Olo” is exclusive to the laboratory requires grasping the basics of color vision.
Here’s a breakdown:
- Cones: Color vision relies on specialized cells called cones in the retina. These cones are sensitive to different wavelengths of light.
- Three Types of Cones: Humans typically have three types of cones, each tuned to respond primarily to red, green, or blue light.
- Overlap and Limitations: The way these cones overlap in thier response to different wavelengths limits the range of colors we can naturally perceive.
How Was “Olo” Created and Perceived in the Lab?
The perception of “Olo” was achieved using a novel technique involving a laser device called “Oz”:
- Targeting the M Cones: Researchers selectively stimulated the M cones (those responsible for green perception) in the retina.
- Precision Technology: This precise stimulation was made possible by sweeping ophthalmoscopy wiht adaptive optics (Aoslo), which mapped the participants’ retinas and allowed for ultra-precise light delivery.
- The Laser Method: The “Oz” laser delivered micro-doses of light to the individual photoreceptors.
what Did “Olo” Look Like?
Participants described “olo” as a greenish-blue tone, more saturated and intense than the color of green water. It exists beyond the typical spectrum.
Did Scientists confirm “Olo” as a New Color?
Yes.researchers conducted a color comparison test.Participants compared “Olo” with adjustable colors. The closest matches were green, but “Olo” required the addition of white light to approximate. This provided validation by indicating its distinctness.
Is “Olo” Just a More Saturated Green? The Expert Debate
That is a matter of debate:
- John Damaged’s viewpoint: The vision researcher believes that “Olo” is “a more saturated green” experienced under conditions.
- Manuel Spitschan’s view: The researcher praised the experiment’s technical sophistication, calling it a “revolutionary advance” in understanding color vision.
What Technology Was Used to Discover “Olo”?
The primary technology used was a laser device called “Oz” coupled with adaptive optics. This system allowed researchers to deliver micro-doses of laser light to individual photoreceptor cells in the retina, activating only the targeted cones (specifically, the M cones responsible for green perception).
Could This Technology Help People with Colorblindness?
Scientists believe that the OZ technology has potential for broad applications, including aiding individuals with colorblindness (Daltonism). It could assist in seeing colors more accurately.
What Are the Key Differences Between Standard Color Perception and “Olo”?
The fundamental difference lies in the method of stimulation.In standard color perception, light from the habitat naturally stimulates retinal cones. In the “Olo” experiment, the M cones are selectively stimulated using a laser, bypassing the usual limitations of the color spectrum.
Key Points Summary Table
| Feature | “Olo” Color | Typical Color Perception |
|---|---|---|
| Environmental Presence | Not visible in the natural world | Visible in Everyday Life |
| Stimulation Method | Direct laser stimulation of M cones | Natural light stimulation of cones |
| Typical Experience | Highly saturated, greenish-blue | A wide range of visible colors |
| Primary application | Scientific research, perhaps therapeutic | Everyday human visual experience |
What’s Next for “Olo” Research?
While the immediate accessibility of “Olo” is limited to the lab, future research will likely focus on understanding the mechanisms of color vision. Researchers will also explore the potential therapeutic applications of OZ technology, especially for people who have color vision deficiencies.
This is a groundbreaking study that underscores the complexity and the potential of human vision. As research continues, we can expect even more incredible discoveries—perhaps even more colors beyond our current perception.
