+In `tailwind.config.js`:
+
+```
+const { colors } = require('tailwindcss/defaultTheme')
+
+module.exports = {
+  purge: ["./public/**/*.html"],
+  theme: {
+    extend: {
+      colors: {
+        // Remove the "gray" colours from the theme.
+        gray: {},
+
+        // Create a new set of "grey" colours, using the original "gray" values.
+        grey: colors['gray']
+      }
+    },
+  },
+  variants: {},
+  plugins: [],
