I’m very excited about this. It will allow us to:

• Define colors in new color spaces like oklch & display-p3
• Convert colors between spaces
• Mix & manipulate colors in any space
• Gamut-map colors for a target space as needed

Safari is the farthest along in terms of browser support for the new color spaces, but this is all part of Interop 2022 – which means every browser is trying to get it done this year. I recommend installing the latest Safari Technology Preview, and playing around with all the new colors!
