A team of scientists in the United States has reported the potential discovery of a new color, tentatively named “Olo,” through experiments involving laser stimulation of the eye.The findings,while intriguing,are prompting debate within the scientific community.
Laser Experiment Sparks New Color Perception
The research involved directing precisely calibrated laser pulses into the eyes of study participants. By selectively stimulating specific cone cells within the retina, the researchers aimed to evoke color perceptions beyond the range of normal human vision. Participants described the resulting sensation as a unique blue-green hue, which the team has labeled “Olo.”
The study, published in Science Advances, details the experimental setup and the subjective experiences of the participants. Ren Ng, a professor at California University and one of the study’s authors, characterized the results as “remarkable.”
Potential Implications for Color Blindness Research
Ng and his colleagues suggest that this research could pave the way for new approaches to understanding and potentially treating color blindness. By manipulating the stimulation of cone cells, scientists may gain insights into how the brain processes color information and how to correct deficiencies in color perception.
Speaking on BBC Radio 4, Ng, who also participated in the experiment, described Olo as a color “more saturated than anything we can see in the real world.” He illustrated the novelty of the color by comparing it to encountering an intensely vibrant shade of pink unlike any previously experienced.
Skepticism and Interpretation
However, the claim of discovering a new color is not without its critics. some experts argue that the perceived color might potentially be a matter of interpretation rather than a fundamentally new visual sensation.
John Barbur,a vision scientist at City St. George’s,University of London,who was not involved in the study,acknowledged the research as a “technology achievement” in selectively stimulating cone cells.however, he cautioned that the subjective experience of a new color remains open to debate. Barbur explained that stimulating red cone cells (L) in large quantities might create a sensation of “dark red,” with brightness varying based on the cone cell’s sensitivity.
Study Details
The experiment involved five participants – four men and one woman – all with normal color vision. Three of the participants, including Ng, are authors of the research paper. The participants used a device called OZ, consisting of mirrors, lasers, and optical components, originally designed by researchers at UC Berkeley and Washington University and afterward updated for this study.
Retinal Function and Cone Cells
The retina, a light-sensitive layer of tissue at the back of the eye, is responsible for processing visual information. it converts light into electrical signals that are transmitted to the brain via the optic nerve. Within the retina are cone cells, which are crucial for color perception. There are three types of cone cells – S, L, and M – each sensitive to different wavelengths of light, corresponding to blue, red, and green.
Normally, stimulation of M cells also stimulates adjacent L and/or S cells due to overlapping function. However, in this study, the laser selectively stimulated only M cells, potentially sending color signals to the brain that do not occur in natural vision.
To validate the perceived colors,participants were asked to adjust a color dial until it matched their perception of Olo.
Ongoing Research
Despite the technical challenges in perceiving Olo, Ng stated that his team is continuing to investigate the potential applications of this finding, particularly for individuals with color blindness.

Scientists Report Finding of ‘Olo,’ a Potentially New Color: Your Questions Answered
(Intro)
Have scientists truly discovered a new color? This is the question on many minds after the announcement of “Olo,” a hue perceived through laser stimulation of the eye. This article dives deep into the research, exploring the fascinating world of color perception and the innovative methods utilized to potentially expand the boundaries of human vision. Let’s explore the study in an easy-to-understand Q&A format, addressing the most pressing questions and providing valuable insights.
What is “Olo,” the Potential New Color?
“Olo” is the tentative name given to a color perception experienced by participants in a recent scientific study. It’s described as a unique blue-green hue, generated by a specific method of stimulating retinal cells.
How Was “Olo” Discovered? what Experiments where Conducted?
Scientists utilized lasers to stimulate the retina, the light-sensitive layer at the back of the eye. Specifically, they targeted the cone cells, responsible for color vision. By precisely controlling the laser pulses, researchers aimed to evoke color perceptions outside the normal range of human vision. This selective stimulation of M (medium wavelength) cone cells, which are normally stimulated with other cone cells, lead to the perception of “Olo.”
Who Conducted the “Olo” Research?
The research was conducted by a team of scientists in the United States. The study’s authors include Professor Ren Ng of California University, along with others in the scientific domain.
What Kind of Device Did the Scientists Use for Their experiment?
The experiment used a device known as “OZ” which was comprised of mirrors, lasers, and other optical components. It was originally designed by researchers from UC Berkeley and Washington University and was updated for the study that led to the discovery of ”Olo.”
What Do Participants Say “Olo” Looks Like?
Participants described “Olo” as a unique blue-green hue. according to one of the study’s authors,Ren Ng,”Olo” is a color “more saturated then anything we can see in the real world.” He compared the experience to encountering a vibrantly saturated pink shade.
Why is this Discovery Considered Controversial? What is the Skepticism?
While the research is intriguing, some experts express skepticism. The primary concern is whether “Olo” truly represents a fundamentally new color sensation, or simply an interpretation of existing color details by the brain. Some experts argue that this perceived color is based on the specific stimulation patterns and might potentially be seen as a “dark red” dependent on the sensitivity of the cone cells being stimulated.
What Role Do cone Cells Play in Color Perception?
Cone cells are critical for color perception. There are three types of cone cells—S, L, and M—sensitive to blue, red, and green wavelengths respectively and all located in the retina. These cells convert incoming light into electrical signals that the brain interprets as color. In the “Olo” experiment, the scientists specifically focused on M (medium wavelength) cone cells to experiment with color perception.
What are the Potential Implications of the “Olo” Research?
The researchers believe that this research could lead to new approaches for understanding and potentially treating color blindness. By manipulating the stimulation of cone cells, scientists may gain insights into how the brain processes color information and how to correct deficiencies in color perception. Understanding how we perceive color could also improve the accuracy of the process.
Does this Research have Clinical Benefits?
The research could allow researchers to understand the process of color blindness and allow them to help improve color-matching processes. The study enables them to investigate the role of cone cells and correct color perception.
What’s Next for the “Olo” Research?
the team is continuing to investigate the potential applications of their findings, especially for individuals with color blindness. They are researching the clinical implications and trying to reproduce findings for various study populations.
(Conclusion)
The discovery of ”Olo “opens up further inquiry into the intricacies of human vision. Although the study is not without critics, the implications of the discovery can be far-reaching as the scientific community continues to explore how we perceive color and how to remedy issues with color vision.
