A new discovery in science has been made that could change the color spectrum as we know it. According to a study by scientists at the University of California, Berkeley and the University of Washington, humans could now observe a range of colors that were not previously known.
A device that displays colors that have never been seen before. This device is known as Oz, which stimulates the cells of the retina in a specific way to see colors differently.
This was the way in which a previously unknown shade was discovered. A hybrid color between blue and green that the researchers have defined as 'Olo'.
New colors by manipulating individual L, M and S photoreceptors
In the human eye there are the L, M and S cones, which until now have been impossible to function in any way other than simultaneously. Oz has managed to activate only the M cone, generating a color that the brain interprets as new.
This color was unknown until April 2023, thanks to the discovery after tests by researchers at the University of California and the University of Washington. The scientists subjected Olo to a color matching test. In these tests, the subjects were unable to match Olo with any conventional color without adding white light.
A color "more saturated than any color you can see in the real world," according to the five privileged people who were able to observe it. "We predicted from the outset that it would look like an unprecedented color signal, but we didn't know what the brain would do with it," the researchers said after discovering this new color.
Based on this way in which the Olo has been discovered, a whole range of possibilities now opens up to create new color tones not based on traditional spectral mixing but on the creation of colors by manipulating the activation of each individual photoreceptor.
