+## Theme colors
+
+You can easily modify the theme color by changing the primary attribute in the tailwind config file:
+
+```:tailwind.config.js
+theme: {
+    colors: {
+      primary: colors.teal,
+      gray: colors.trueGray,
+      ...
+    }
+  ...
+}
+```
+
+The primary color attribute should be assigned an object with keys from 50, 100, 200 ... 900 and the corresponding color code values.
+
+Tailwind includes great default color palettes that can be used for theming your own website. Check out [customizing colors documentation page](https://tailwindcss.com/docs/customizing-colors) for the full range of options.
+
+Migrating from v1? You can revert to the previous theme by setting `primary` to `colors.sky` (Tailwind 2.2.2 and above, otherwise `colors.lightBlue`) and changing gray to `colors.coolGray`.
+
 ## Layouts
 
 You can map mdx blog content to layout components by configuring the frontmatter field. For example, this post is written with the new `PostSimple` layout!
