We don’t need to tell you that accessibility is important for a Design System, right? Luckily one of the most important aspects of accessibility, color, has gotten a little easier to tackle.

You could also try https://palx.jxnblk.com/ (very simple) or colorbox.io (bit more complex), both help with creating accessible color-systems. Or you can just use AI to generate a color palette for you: http://khroma.co/generator/
