Can I Use

Works in

IE9+

Should you use css3 colors in 2026?

You have to specify a fallback color for IE 8- users. Use the hsl(), hsla() and rgba() functions with more caution, as they may not be supported on older browsers.

How to use it

.panel { background: rgb(15 23 42 / 0.8); }   /* space-separated, with alpha */
.brand { color: hsl(217 91% 60%); }

Polyfills and fallbacks

Progressive enhancement works well here: browsers without support degrade gracefully, so a dedicated polyfill is usually unnecessary.
