We're working on adding colors for folders in CryptDrive (https://github.com/xwiki-labs/cryptpad/issues/383) and trying to decide on a color palette.
While there are lots of resources available for choosing small palettes which are accessible to people with colorblindness, we're having trouble finding larger ones (16-20 colors) which are still pleasant enough that people won't yell at us for being bad designers.
Can anyone point us in the right direction?
A member of our team installed the "let's get colorblind" extension for firefox: https://addons.mozilla.org/en-US/firefox/addon/let-s-get-color-blind/
It gives you an idea of what different people will see, but doesn't go so far as to offer a preconfigured set of colors that people could adopt.
For example, I know if I want to choose a font which will be easier to read for people with dyslexia I can use https://opendyslexic.org/
From what I can tell there's no ready solution for accessible color palettes.
