PostCSS Color Mix Function

npm install @csstools/postcss-color-mix-function --save-dev

PostCSS Color Mix Function lets you use the color-mix() function following the CSS Color 5 Specification.

.purple_plum {
	color: color-mix(in lch, purple 50%, plum 50%);
}

/* becomes */

.purple_plum {
	color: rgb(175, 92, 174);
