+This should override an RGB LED when app status has warnings or errors, and then restore its state when status is OK.
+
+```yaml
+# example configuration:
+
+switch:
+  - platform: color_status_led
+    name: Color Status LED
+    light: my_light
+```
+
+Eventually, this functionality should be folded back into the core `status_led` platform.
