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.
- adzm 11mo agoYou can choose other color spaces here which is neat and helps visualize this a bit more accurately.
- madcaptenor 11mo agoHere's the list of colors it works off of: https://github.com/meodai/color-names/blob/main/src/colornames.csv https://github.com/meodai/color-names/blob/main/src/colornam... I'm trying to figure it out.
- madcaptenor 11mo agoFor 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.
- meodai 11mo agooh Id love to add this to the tooling of the color names list. How did you figure out what the largest gap was?
- madcaptenor 11mo agoPick points at random, then use a general-purpose optimization method (the optim function in R) to find local maxima. I don’t claim this is a good way to do it.
- turtletontine 11mo agoperceptual 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.)
