Berkeley Researchers Discover ‘Olo,’ a color Beyond Human Perception
BERKELEY, Calif.(AP) — Move over, Mocha Mousse. A team at the University of California, Berkeley, has perhaps expanded the boundaries of human color perception with the discovery of a new color, dubbed “olo.” While it’s unlikely to appear in everyday life, the finding highlights the limitations of human vision compared to other species.
Expanding the Spectrum: Laser Stimulation Unlocks New Color
Humans possess a limited range of color perception. However,by stimulating retinal cells with a laser,researchers were able to access a previously unknown color space. This led to the identification of olo, a hue described as existing between turquoise and water green.
“We anticipated an unprecedented color signal,” said Ren Ng, an electrical engineer at UC Berkeley, speaking to the *Guardian*. “But we weren’t sure how the brain would react.”
Seeing olo is unfeasible without the specialized laser stimulation. Researchers offered a turquoise box as a close approximation, but emphasized it doesn’t accurately represent the true color.
“There is no way to ‘transmit’ that color in an article or on a monitor,” said scientist Austin Roorda. “The point is that this is not the color we see, but a clearly ‘version’ of his more pale compared to the experience of Olo ‘.” He added, “It is indeed a color incredibly saturated.”
The Science of Color Perception
Human color perception relies on cone cells in the retina,which are sensitive to different wavelengths of light. There are three types of cones: long (L), medium (M), and short (S). natural light comprises various wavelengths that stimulate these cones differently. Red light primarily stimulates L cones,while blue light mainly activates S cones.
The color olo is unique because it results from stimulating only the M cones, a feat not achievable with natural light. The name “olo” derives from the binary code 010, representing the activation of only the M cones.
Implications for Vision Research
The technology enabling this expanded chromatic perception, named ’Oz Vision,’ could revolutionize research into visual perception. It may provide insights into how the brain constructs visual experiences and shed light on conditions such as colorblindness and retinal diseases.
berkeley Researchers Discover ‘Olo,’ a Color Beyond Human Perception
This article explores the groundbreaking discovery of “olo,” a new color beyond human perception, unveiled by researchers at the University of California, Berkeley.
What is ‘Olo’?
What is ‘olo,’ and where does its name come from?
‘Olo’ is a newly discovered color, a hue that, according too the article, is described as existing between turquoise and water green. The name “olo” is derived from the binary code 010, which corresponds to the activation of only the M (medium) cones in the retina.
How Was ‘Olo’ Discovered?
How did researchers discover a new color that humans couldn’t see before?
Researchers at UC Berkeley were able to stimulate retinal cells using a laser. This allowed them to access a previously unknown color space and identify “olo.”
Can I see ‘olo’ on my computer screen or in everyday life?
No, seeing ‘olo’ is not possible without the specialized laser stimulation used in the research. The researchers offered a turquoise box as an approximation, but this does not accurately represent the true “olo” color. As scientist Austin Roorda stated, “There is no way to ‘transmit’ that color in an article or on a monitor.”
How does this discovery relate to the limitations of human vision?
The discovery of ‘olo’ highlights the limitations of human color perception compared to other species.Our vision, as it is indeed, relies on a specific set of biological components.
The science Behind seeing Color
How do humans perceive color?
Human color perception relies on cone cells in the retina,which are sensitive to different wavelengths of light.
What are the different types of cone cells, and what do they do?
There are three types of cone cells:
Long (L) cones: Primarily stimulated by red light.
medium (M) cones: Primarily stimulated in the discovery of olo.
Short (S) cones: Primarily stimulated by blue light.
What makes the color ‘olo’ unique?
The color ‘olo’ is unique as it results from stimulating only the M cones, a feat not achievable with natural light. The binary code 010 represents the activation of only the M cones.
Implications and Future research
What are the implications of this discovery for vision research?
The technology enabling this expanded chromatic perception, named ‘Oz Vision,’ could revolutionize research into visual perception. It may provide insights into:
How the brain constructs visual experiences.
Conditions such as colorblindness.
Retinal diseases.
Summary of Color Perception
| Feature | Description |
