UC Berkeley scientists tricked the eye into seeing "the greenest green" they'd ever seen. They say it could transform how we understand and treat eye diseases, and expand the way we see the world around us.
“There’s no light in nature that can only stimulate the M-cones,” said Austin Roorda, a professor of optometry and vision science at the School of Optometry at Berkeley.
Roorda explained that the human eye has long, middle and short wavelength-sensitive cones called L, M and S cones. The M cones are sandwiched between the L and the S cones, so when the M cone is tickled, so are the L and the S.
The study involved a team of researchers, including Ren Ng, a professor of electrical engineering and computer sciences at Berkeley. Their collaboration began years ago when Ng asked Roorda, “What would happen if we delivered light to thousands of M cones only? Would it be the greenest green you’ve ever seen?”
So it’s essentially isolated green or “pure” green.
I seem to remember reading it’s so named because only the “G” in the (roughly) RGB cones are stimulated, so a 0-1-0 mapping onto the R-G-B colour space. 0-1-0 > olo.

So olo because it’s the middle of color?

Another name for it is “olou”

It’s not easy seeing green.
Has the same thing been done for the L and S cones? I mean, the isolated “tickling”?
As far as i understand, it’s easier to be on either end of the spectrum, so there are already colors that do that in nature.
I’m curious as well, for all we know we don’t know what pure red looks like either.
