This is great, thank you for sharing. I need something like this for my current project I'm working on... Much easier than trying to build a color palette manually.

I also recommend Color Brewer, which is integrated already in a lot of visualization tools, and has great options for display variants and accessibility options : https://en.wikipedia.org/wiki/ColorBrewer

It's functionally very close to https://colorbrewer2.org, which has been online for more than 15 years. I think it's not a coincidence, and some credits wouldn't have hurt anyone...

Also, I have personally been using iWantHue to generate large palettes for more than 10 years now, and I'm still very happy about it: https://medialab.github.io/iwanthue/

See Fabio Crameri's colour maps for accessible yet pleasing schemes and gradients to accustom various vision impairments [0][1]. Ben Jann's collection also provides a valuable resource and inventory of recent and historic colour schemes included in different statistical packages [2].

Definitely not colorblind-friendly (color contrast too low)

The default palette essentially is IBM's Color-blind safe[0], which does provide some 'safe' defaults. IBM's design guidelines provide some sound advice for color use too [1].

Whenever I need colors for a chart, I type "12 bit" in my address bar and pray my browser hasn't forgotten the URL: https://iamkate.com/data/12-bit-rainbow/
