#colors
u/lionleaf

Beautiful! Broken on #Edge and some other #browsers though. Should be possible to fix, but tagging it now so it's easy to find later :)
u/mvs202

Yeah, the problem is Edge doesn't like the 4th parameter in hsl() - I would need hsla() for that. Surprisingly, no one bothered by the lack of a closing paran in the hsl function!
