- Since colors are an activation of rods and cones, could we simulate them by stimulating the eye nerves directly? Not necessarily to see new colors, but to replicate the experience of sight? If we managed that, wouldn't it feel exactly the same as seeing something in nature that itches the back of the eye so nicely? I suppose this is entering the brain interface territory.by xpct
- > 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?
by zahlman - 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.by amoshebb
- I wonder why if this is the reason for the icon color of the game Olo. The left half of the icon background looks so similar.

- Reminds me a bit of a Greg Egan story from Instantiation called Seventh Sight. Kids with artificial eyes hack them to see colors and spectrum not perceptible by humans.by jeremyjh
- Aha! I was trying to figure out the colour of the E5/H5 Shinkansen that are used on the Tokyo-Morioka-Aomori (Hayabusa/Yamabiko) line. This is it.

- The closest approximation to Olo colored paint you can buy is also by the company that makes some of the blackest black paint. I haven't used it personally. https://culturehustle.com/collections/paint/products/yolo-ne...by hdz

by kridsdale1 - There is no "olo-colored" anything; that's the whole point. This is bordering on a scam.by 22039dj9j3d
- Note that there has been controversy for the last few years around Culture Hustle not fulfilling orders and doing other sketchy things. Just a heads up.by jhiesey
- They also make the orangiest orange paint, the yellowest yellow, the pinkest pink, etc. At a certain point I have to wonder how much these are accurate descriptors of the paint colors vs arbitrary made up marketing nonsense.by c22
- Is it too late to rename it to Octarine?by drayfield
- My thoughts as soon as I saw the title :)by Razengan
- I thought of "The Colour Out of Space".
- +1 for the Sir Terry reference.
I suspect many animals experience color quite differently, including seeing infrared/ultraviolet, etc.
- In my headcanon octarine is a colour between orange and deep purple. Sometimes it has a hazy blackish halo.by phikappa
- If you are interested in "imaginary" colors, the gamut is actually well-specified, and (I hope it is appropriate to comment) that I made a visualization where you can drag a selection thumb over the gamut to see the "simulated" version of that color. Also include it is a 12-step contrast-sensitive color palette generator for said imaginary colors, which would allow you to make websites and (say) vscode themes using entirely imaginary colors! https://docs.moment.dev/d/hausdorff/2zmqjlmldchela29xvbzlbki...by antics
- 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':
