Description
I usually look up palettes and the UI comes out nice except some color pairs don't pass wcag color contrast and well - just isn't readable Ended up writing a tiny library that automatically nudges your text color just enough to pass AA or AAA, while keeping it visually similar to the original along with a color contrast linter so we can use it in CI Thought you guys might find it useful too, it's foss :>

Yes Cm-colors is a focused color manipulation utility calculating WCAG relative luminance contrast ratios and algorithmically stepping HSL/RGB values to meet target ratios.

Same idea, different domain
Nobody's really built a dev tools tool for Sales yet.
