Miro presentations are limited to the washed out colors of hex, and are hard to make both beautiful and accessible/inclusive.
OKLCH supported in CSS, and is being adopted big time.

oklch() is a new way to define CSS colors. In oklch(L C H) or oklch(L C H / a) each item corresponds as follows: L is perceived lightness ( 0% - 100% ). “Perceived” means that it has consistent lightness for our eyes, unlike L in hsl() . C is chroma, from gray to the most saturated color.
