Hi Alexei, thanks for your work on HSLuv! I love the simplicity of it, where you can use HSLuv as mostly a drop-in replacement for HSL which most designers are familiar with.

I keep seeing new tutorials on designing accessible palettes that still use HSL, where the WCAG2 contrast breaks and goes all over the place as you vary the hue and saturation. HSLuv makes life so much easier here and lets you focus on exploring colors that you know will pass, using a familiar looking color picker.
