I would love to see such tools have some accessibility DX built-in. The idea is to define the color palette in such a way that we know whether a color combination is accessible just by looking at the color name. For example, using the USWDS design system, I know that blue-30 on gray-80 is accessible (WCAG AA), because the difference between both values is 50+.<p>I once wrote a blog post about this (niche) concept: <a href="https://darekkay.com/blog/accessible-color-palette/" rel="nofollow">https://darekkay.com/blog/accessible-color-palette/</a>
