 ### The 'nightwind-prevent' class
 
 Sometimes you want an element to remain exactly the same in both light and dark modes. You can achieve this in Nightwind by adding a 'nightwind-prevent' class to the element.

+### Custom color scale
 
-Variants and other color classes can be enabled for Nightwind like so:
+This configuration allows you to define how one or more color weights convert in dark-mode. Note that these **affects all color classes**.
+
+For example, you could make all -100 colors convert into -900 colors like so.
 
 ```js
 // tailwind.config.js
 module.exports = {
-  // ...
-  variants: {
+  theme: {
     nightwind: {
-      variants: ["focus"], // Add any Tailwind variant
-      colorClasses: [
-        "gradient",
-        "ring",
-        "ring-offset",
-        "divide",
-        "placeholder",
-      ],
+      colorScale: {
+        100: 900, // default 800

-The 'gradient' color class enables Nightwind for the 'from', 'via' and 'to' classes, allowing **automatic dark gradients**.
+> Note: These settings can still be overridden for specific colors using [color mappings](#color-mappings), or in specific elements with [overrides](#overrides)
+
+#### Reduced preset
+
+This preset simulates how Nightwind would behave without the -50 color classes. Any -50 color will essentially appear the same as -100 colors (both becomes -900)
+
+This behaviour may be desirable for two main reasons:
+
+- Makes the reversed -800 and -900 colors darker and more different between themselves.
+- -500 colors remain the same in both dark and light mode
+
+```js
+// tailwind.config.js
+module.exports = {
+  theme: {
+    nightwind: {
+      colorScale: {
+        preset: "reduced",
+      },
+    },
+  },
+}
+```
+
+This is the corresponding scale:
+
+```js
+// tailwind.config.js
+colorScale: {
+  50: 900,
+  100: 900,
+  200: 800,
+  300: 700,
+  400: 600,
+  500: 500,
+  600: 400,
+  700: 300,
+  800: 200,
+  900: 100,
+},
+```
+
+> Note: When using a preset, specific weights will be ignored.
