I use a similar app called Name That Color — https://chir.ag/projects/name-that-color/#6195ED I like sharing descriptive names with designers instead of naming everything "light blue" "dark blue" "not quite as light but still not dark blue" etc. This new thing is tons of fun but seems a bit less practically useful.

You just reminded me that my app turned 18 a few months ago.

Another dev, Daniel Flück, extended the app to help color blind users: https://www.color-blindness.com/color-name-hue/

What coordinate in the space is furthest from any named color? It looks like there are some relatively large voids in the blue/purple boundary area but it’s hard to say.

Here's the list of colors it works off of: https://github.com/meodai/color-names/blob/main/src/colornam...

I'm trying to figure it out.

perceptual distance is quite different from Euclidean distance in this RGB space. Like if put two swaths of color side by side and said “how similar are these?” to samples of people, the groupings would not much resemble this cube.

They’ve done this! It’s shown on a “chromaticity diagram”, and is useful for comparing what colors different screens/printers/etc can reproduce. (It’s 2D not 3D cause it’s normalized for luminance or brightness.) Color science is weirdly fascinating:

Wish there was a way to make it stop spinning, it's practically impossible to figure out adjacent colors because everything keeps moving no matter what you do. Perhaps there is a way, but I didn't find it?

Only change is lines 421 + 422 that sloooowly rotated the cube are commented out in the javascript, otherwise should act the same!

For Euclidean distance it seems to be in the neighborhood of (59, 250, 60) which is a bright green, although of course Euclidean distance is not perceptual distance. The blue at (57, 42, 214) also is up there.

You can choose other color spaces here which is neat and helps visualize this a bit more accurately.
