The new [Color Module 5 working draft](https://www.w3.org/TR/css-color-5) introduce new css functions to manipulate colors: - [`color-adjust()`](https://www.w3.org/TR/css-color-5/#coloradjust) - [`color-mix()`](https://www.w3.org/TR/css-color-5/#colormix) - [`color-contrast()`](https://www.w3.org/TR/css-color-5/#colorcontrast) Would you consider to "revive" this plugin (or make new ones) in order to support the new spec? >**Warning** This repo is deprecated and postcss-preset-env are moved to monorepo. Here the mirror issue. https://github.com/csstools/postcss-plugins/issues/177
