+If you want to customize the color scheme of the theme to give it your individual touch you are just a few lines CSS away. In general, you have to override the defaults, the easiest way to do so is to create a `static/custom.css` file right in your site root.
+
+All necessary class names are listed below. If you miss some classes for theming you are very welcome to fill an [Issue](https://github.com/xoxys/hugo-geekdoc/issues). For some inspiration you can have a look at [https://www.color-hex.com/color-palettes/](https://www.color-hex.com/). The following listing use the _HC-primary_ color palette as an example:
+
+{{< highlight CSS "linenos=table" >}}
+/* defaut link color */
+a { color: #1c388e; }
+a:visited { color: #73bfb8 }
+
+/* site header */
+.gdoc-header { background: #e66a4e; border-color: #404040; }
+.gdoc-header__link, .gdoc-header__link:visited { color: #ffffff; }
+
+/* page links */
+.gdoc-page__footer a, .gdoc-page__footer a:visited { color: #1c388e; }
+.gdoc-page__header a, .gdoc-page__header a:visited { color: #1c388e; }
+
+/* site footer */
+.gdoc-footer { background: #404040; color: #ffffff; }
+.gdoc-footer__link{ color: #fecf50; }
+.gdoc-footer__link:visited, .gdoc-footer__link:hover { color: #fecf50; }
+
+/* custom shortcodes */
+/* button */
+.gdoc-button { color: #495057; }
+.gdoc-button:hover { background-color: #eb8771; border-color: #e66a4e; color: #ffffff; }
+
+/* hint */
+.gdoc-hint.info { background: #d1d7e8; border-color: #324b99; color: black; }
+.gdoc-hint.warning { background: #fef5dc; border-color: #e4ba48; color: black; }
+.gdoc-hint.danger { background: #fae1db; border-color: #cf5f46; color: black; }
+{{< /highlight >}}
+
+And that is how the result will looks like. Happy theming!
