> Olo was discovered on April 18, 2025 by scientists at UC Berkeley.[1][3] The color is named after its theoretical LMS color space coordinates (0, 1, 0), which spells "olo" in leet speak.[4][3] I presume "loo" and "ool" are in-gamut? What hex values?

703 nm laser is almost “loo”, and 417 nm is almost “ool”. Searching those wavelengths gives me #FF0000 and #6400FF. Loo is all red and ool is all violet.

This is heroin for the eyes. Once the hit is over you want to take another one and if you don't it'll take ten minutes or so until the "real" world won't feel like a bleached sepia picture any more.

I saw the blue rim, but I didn't notice much effect on how the real world looked like after. But then, I'm red-green colourblind.

Now I remembered how you see this color. You stare the some shape of 0xFF0030 and then close yores eyes and the inverted color appears.

It is possible to see something close (how close I don't know) by saturating the S & M cones instead of avoiding them. Wikipedia refers to these as 'chimerical colors': https://en.wikipedia.org/wiki/Impossible_color#Chimerical_co...

These demos really drive home the chemical / biological part of visual perception to me. As I perceive these strange new colors I can almost feel the chemical processes occurring in my cones.

Love this - references one of my favorite ever optical experiences Eclipse of Titan https://www.skytopia.com/project/illusion/ipage-et.html

BTW olo was not discovered in 2025

In ~2016 on the chan someone posted a completely unhinged post about this "bleen" "grue" color that nobody could see. it's probably lost to the ages now, but I remember it.

tbf it's more like methylamine + P2P meth for the eyes

Are you sure that wasn't referencing "grue" from this philosophical thought experiment? https://en.wikipedia.org/wiki/New_riddle_of_induction
