+3. Optional : Override default colors with `stylesheet` attribute : 
+
+```css
+header {
+    --georchestra-primary: #124885;
+    --georchestra-secondary: #83532b;
+    --georchestra-primary-light: #12488540;
+    --georchestra-secondary-light: #83532b40;
+  }
+```
+
+Note: It's important to target the `header` tag here to override the css variables, because of the shadow DOM.
