Meet "olo": a vivid, hyper-saturated blue-green that can't be captured by screens or paint.

"The whole point is that this is not the color we see, it’s just not," said Austin Roorda, a vision scientist who authored the study that appeared in the journal Science Advances last week.

Not everyone is convinced that olo is truly a new color, however. John Burbur, a vision researcher at the University of London, tells the Guardian that the work has “limited value.” ...

The study, published Friday in Science Advances, involved five adults with normal color vision—four men and one woman. Three of them, including Professor Ren Ng of the University of California, also ...

and its existence is redefining the boundaries of human color vision. The discovery of olo was made possible through a pioneering technique involving precise laser stimulation of the retina.

A powerful new instrument added to the Daniel K. Inouye Solar Telescope promises to maximize the information gleaned from the ...

In theory, the technique could also be used to simulate full-color vision in people who are color-blind, essentially compensating for their missing or defective photoreceptors. By using the system ...

These red, green and blue signals travel to the brain, where they’re combined into the full-color vision we experience. But these three cone types handle overlapping ranges of light: the light ...

The newly described method and prototype machine is called the Oz Vision System,(a not-so-subtle nod to reaching somewhere over the rainbow. And the new color enabled by Oz is named “olo,” a ...
