+# Color System
+
+**@ohif/ui** offers a color system with a handful of color utility classes.
+
+As **@ohif/ui** uses Tailwind as a base styling library, you will be able to use
+all the default colors from Tailwind, besides our custom colors too.
+
+# How to use
+
+To apply color in your element, you will use the same way Tailwind does.
+
+- Background - `bg-primary-main`
+- Border - `border-primary-main`
+- Text - `text-primary-main`
+- Placeholder - `placeholder-primary-main`
+
+Check [Tailwind's documentation](https://tailwindcss.com/docs) to see more
+details about color classes.
+
