+/**
+ * Colors
+ *
+ * Each colors have exact same color scale system with 3 levels of solid
+ * colors with different brightness, and 1 soft color.
+ * 
+ * - `XXX-1`: The most solid color used mainly for colored text. It must
+ *   satisfy the contrast ratio against when used on top of `XXX-soft`.
+ *
+ * - `XXX-2`: The color used mainly for hover state of the button.
+ *
+ * - `XXX-3`: The color for solid background, such as bg color of the button.
+ *   It must satisfy the contrast ratio with pure white (#ffffff) text on
+ *   top of it.
+ *
+ * - `XXX-soft`: The color used for subtle background such as custom container
+ *   or badges. It must satisfy the contrast ratio when putting `XXX-1` colors
+ *   on top of it.
+ *
+ *   The soft color must be semi transparent alpha channel. This is crucial
+ *   because it allows adding multiple "soft" colors on top of each other
+ *   to create a accent, such as when having inline code block inside
+ *   custom containers.
+ *
+ * - `default`: The color used purely for subtle indication without any
+ *   special meanings attched to it such as bg color for menu hover state.
+ *
+ * - `brand`: Used for primary brand colors, such as link text, button with
+ *   brand theme, etc.
+ *
+ * - `tip`: Used to indicate useful information. The default theme uses the
+ *   brand color for this by default.
+ *
+ * - `warning`: Used to indicate warning to the users. Used in custom
+ *   container, badges, etc.
+ *
+ * - `danger`: Used to show error, or dangerous message to the users. Used
+ *   in custom container, badges, etc.

+# Runtime API Examples
+
+This page demonstrates usage of some of the runtime APIs provided by VitePress.
+
+The main `useData()` API can be used to access site, theme, and page data for the current page. It works in both `.md` and `.vue` files:
+
+```md
+<script setup>
+import { useData } from 'vitepress'
+
+const { theme, page, frontmatter } = useData()
+</script>
+
+## Results
+
+### Theme Data
+<pre>{{ theme }}</pre>
+
+### Page Data
+<pre>{{ page }}</pre>
+
+### Page Frontmatter
+<pre>{{ frontmatter }}</pre>
+```
+
+<script setup>
+import { useData } from 'vitepress'
+
+const { site, theme, page, frontmatter } = useData()
+</script>
+
+## Results
+
+### Theme Data
+<pre>{{ theme }}</pre>
+
+### Page Data
+<pre>{{ page }}</pre>
+
+### Page Frontmatter
+<pre>{{ frontmatter }}</pre>
+
+## More
+
+Check out the documentation for the [full list of runtime APIs](https://vitepress.dev/reference/runtime-api#usedata).
