+# `@img/colour`
+
+The latest version of the
+[color](https://www.npmjs.com/package/color)
+package is now ESM-only,
+however some JavaScript runtimes do not yet support this,
+which includes versions of Node.js prior to 20.19.0.
+
+This package converts the `color` package and its dependencies,
+all of which are MIT-licensed, to CommonJS.
