Who's to say you can't use Sass variables _and_ CSS variables?
My current shop is moving to switch our sass color function `color.get()` to either dump hardcoded hex or a css variable usage based on a param. It currently just does hex.
Well, it was a response to the parents claim that “[w]riting actual CSS is the waste of time”.
You might be happy to learn that CSS color module 4[1] will add `lab()` and `lch()` color definitions and CSS color module 5[2] will add the `color-adjust` function as well as other goodies.
