A couple of table top game designers came together to build an open-source colour identification system that is colorblind friendly. It uses symbols and color theory. For example: the symbol for green is a mix of the one for yellow and blue.
I could totally see those engraved on little wooden tokens for board games for example.
@stephaniewalter Wait there are multiple ways of being colorblind, why do the only have one toggle? how does it function with other forns of colorblindness? do they have a suggested palatte along with their symbols?

EDIT: Wait you literally do UX stuff professionally, you almost certainly know/thought through this already. Okay uh questions are for my "wait, why did they do it like this?" interest; citation is for any third-party reading these comments who sees my question.
