+
+```bash
+npm install @csstools/postcss-gradients-interpolation-method --save-dev
+```
+
+[PostCSS Gradients Interpolation Method] lets you use different interpolation methods in CSS gradient functions following [CSS Images Module 4].
+
+```pcss
+.example {
+	background-image: linear-gradient(in oklch, hsl(0deg 85% 75%) 0%, hsl(180deg 80% 65%) 100%);
+}
+
+:root {
+	--background-image: linear-gradient(in oklab, hsl(96, 42%, 24%) 0%, hsl(302, 67%, 25%) 100%);
+}
+
+/* becomes */
+
+.example {
+	background-image: linear-gradient(rgb(245, 137, 137) 0%, rgb(248, 146, 114), rgb(244, 158, 94), rgb(235, 171, 82), rgb(220, 185, 81), rgb(201, 199, 95), rgb(177, 211, 118), rgb(151, 221, 146), rgb(125, 229, 177), rgb(103, 235, 208), rgb(94, 237, 237) 100%);
+	background-image: linear-gradient(in oklch, hsl(0deg 85% 75%) 0%, hsl(180deg 80% 65%) 100%);
+}
+
+:root {
+	--background-image: linear-gradient(rgb(56, 87, 35) 0%, rgb(64, 83, 46), rgb(70, 79, 54), rgb(76, 74, 62), rgb(82, 69, 68), rgb(86, 64, 75), rgb(91, 58, 81), rgb(95, 51, 87), rgb(99, 44, 93), rgb(103, 34, 98), rgb(106, 21, 104) 100%);
+}
+
+@supports (background: linear-gradient(in oklch, red 0%, red 0% 1%, red 2%)) {
+:root {
+	--background-image: linear-gradient(in oklab, hsl(96, 42%, 24%) 0%, hsl(302, 67%, 25%) 100%);
+}
+}
+```
+
+## Shortcomings
+
+⚠️ Color stops with only a color or only an interpolation hint are not supported.
+
+For best results you should always provide at least the color and position for each color stop.
+Double position color stops are supported.
+
+```pcss
+.foo {
+	/* Only a color: can't transform */
+	background-image: linear-gradient(in oklch, black 0%, green, blue 100%);
+
+	/* Only an interpolation hint: can't transform */
+	background-image: linear-gradient(in oklch, black 0%, 25%, blue 100%);
+}
+```
+
+⚠️ Variable colors are also not supported.
+We can not mix colors when the color is a variable.
+
+```pcss
+.foo {
+	--red: red;
+	/* Color stop variable : can't transform */
+	background-image: linear-gradient(in oklch, black 0%, var(--red), blue 100%);
+}
+```
+
+## Usage
+
+Add [PostCSS Gradients Interpolation Method] to your project:
+
+```bash
+npm install postcss @csstools/postcss-gradients-interpolation-method --save-dev
+```
+
+Use it as a [PostCSS] plugin:
+
+```js
+const postcss = require('postcss');
+const postcssGradientsInterpolationMethod = require('@csstools/postcss-gradients-interpolation-method');
+
+postcss([
+	postcssGradientsInterpolationMethod(/* pluginOptions */)
+]).process(YOUR_CSS /*, processOptions */);
+```
+
+[PostCSS Gradients Interpolation Method] runs in all Node environments, with special
+instructions for:
+
+- [Node](INSTALL.md#node)
+- [PostCSS CLI](INSTALL.md#postcss-cli)
+- [PostCSS Load Config](INSTALL.md#postcss-load-config)
+- [Webpack](INSTALL.md#webpack)
+- [Next.js](INSTALL.md#nextjs)
+- [Gulp](INSTALL.md#gulp)
+- [Grunt](INSTALL.md#grunt)
+
+## Options
+
+### preserve
+
+The `preserve` option determines whether the original notation
+is preserved. By default, it is preserved.
+
+```js
+postcssGradientsInterpolationMethod({ preserve: false })
+```
+
+```pcss
+.example {
+	background-image: linear-gradient(in oklch, hsl(0deg 85% 75%) 0%, hsl(180deg 80% 65%) 100%);
+}
+
+:root {
+	--background-image: linear-gradient(in oklab, hsl(96, 42%, 24%) 0%, hsl(302, 67%, 25%) 100%);
+}
+
+/* becomes */
+
+.example {
+	background-image: linear-gradient(rgb(245, 137, 137) 0%, rgb(248, 146, 114), rgb(244, 158, 94), rgb(235, 171, 82), rgb(220, 185, 81), rgb(201, 199, 95), rgb(177, 211, 118), rgb(151, 221, 146), rgb(125, 229, 177), rgb(103, 235, 208), rgb(94, 237, 237) 100%);
+}
+
+:root {
+	--background-image: linear-gradient(rgb(56, 87, 35) 0%, rgb(64, 83, 46), rgb(70, 79, 54), rgb(76, 74, 62), rgb(82, 69, 68), rgb(86, 64, 75), rgb(91, 58, 81), rgb(95, 51, 87), rgb(99, 44, 93), rgb(103, 34, 98), rgb(106, 21, 104) 100%);
+}
+```
+
+### enableProgressiveCustomProperties
+
+The `enableProgressiveCustomProperties` option determines whether the original notation
+is wrapped with `@supports` when used in Custom Properties. By default, it is enabled.
+
+⚠️ We only recommend disabling this when you set `preserve` to `false` or if you bring your own fix for Custom Properties. See what the plugin does in its [README](https://github.com/csstools/postcss-plugins/tree/main/plugins/postcss-progressive-custom-properties#readme).
+
+```js
+postcssGradientsInterpolationMethod({ enableProgressiveCustomProperties: false })
+```
+
+```pcss
+.example {
+	background-image: linear-gradient(in oklch, hsl(0deg 85% 75%) 0%, hsl(180deg 80% 65%) 100%);
+}
+
+:root {
+	--background-image: linear-gradient(in oklab, hsl(96, 42%, 24%) 0%, hsl(302, 67%, 25%) 100%);
+}
+
+/* becomes */
+
+.example {
+	background-image: linear-gradient(rgb(245, 137, 137) 0%, rgb(248, 146, 114), rgb(244, 158, 94), rgb(235, 171, 82), rgb(220, 185, 81), rgb(201, 199, 95), rgb(177, 211, 118), rgb(151, 221, 146), rgb(125, 229, 177), rgb(103, 235, 208), rgb(94, 237, 237) 100%);
+	background-image: linear-gradient(in oklch, hsl(0deg 85% 75%) 0%, hsl(180deg 80% 65%) 100%);
+}
+
+:root {
+	--background-image: linear-gradient(rgb(56, 87, 35) 0%, rgb(64, 83, 46), rgb(70, 79, 54), rgb(76, 74, 62), rgb(82, 69, 68), rgb(86, 64, 75), rgb(91, 58, 81), rgb(95, 51, 87), rgb(99, 44, 93), rgb(103, 34, 98), rgb(106, 21, 104) 100%);
+	--background-image: linear-gradient(in oklab, hsl(96, 42%, 24%) 0%, hsl(302, 67%, 25%) 100%);
