By default, it is not preserved. ```js postcssColorMixVariadicFunctionArguments({ preserve: true }) ``` ```css .red { color: color-mix(in srgb, red); } .grey { color: color-mix(in srgb, red, lime, blue); } /* becomes */ .red { color: rgb(255, 0, 0); color: color-mix(in srgb, red); } .grey { color: rgb(85, 85, 85); color: color-mix(in srgb, red, lime, blue); } ``` [cli-url]: https://github.com/csstools/postcss-plugins/actions/workflows/test.yml?query=workflow/test [css-url]: https://cssdb.org/#color-mix-variadic-function-arguments [discord]: https://discord.gg/bUadyRwkJS [npm-url]: https://www.npmjs.com/package/@csstools/postcss-color-mix-variadic-function-arguments [PostCSS]: https://github.com/postcss/postcss [PostCSS Color Mix Variadic Function Arguments]: https://github.com/csstools/postcss-plugins/tree/main/plugins/postcss-color-mix-variadic-function-arguments [CSS Color 5 Specification]: https://www.w3.org/TR/css-color-5/#color-mix --- _Source: https://npm.io/package/@csstools/postcss-color-mix-variadic-function-arguments · Machine-readable twin of the npm.io package page.
