 ### Update accent colors
 
-The accent colors can be updated using the ```update_accent_colors()``` function. This function will retrieve the values again.
+The accent colors can be updated manually using the ```update_accent_colors()``` function. This function will retrieve the values again.
+
+### Accent color change listener
+This module allows you to add a listener that will call a specific function when the accent color changes. Here's how you can add it:
+
+```python
+import winaccent, threading
+
+# Replace `callback` with the function that you want to be called
+thread = threading.Thread(target = lambda: winaccent.on_accent_changed_listener(callback), daemon = True)
+thread.start()
+```
+
+> [!NOTE]
+> If you added the listener, there's no need to call `update_accent_colors` because it will be called automatically every time the accent color changes.
