Every ‘color’

There’s been a lot of exciting work in the CSS color specifications lately, and the new features are starting to land in browsers – so we’ve been preparing to add support in Sass as well.

Browsers are starting to roll out support for new color spaces in CSS as part of Interop 2022. My proposal for the Sass implementation is live, and ready for feedback.

Working on Sass support for color spaces, I ran into a question about the proper handling of hwb() colors. That lead me down a rabbit hole, exploring the edges of hwb (and powerless color channels) in CSS.
