What are OKLCH colors?
I enjoyed this short post on OKLCH colours by Jakub Krehel.
If you are on a display that supports Display-P3, you will see the right colors more vivid than the left ones. If you are on a display that only supports sRGB, the colors should look nearly identical, as the browser maps the out of gamut color back inside the sRGB gamut.

I also enjoyed playing with the tool Jakub built to explore OKLCH.
