+You can reflect the `ha-card` state by using `jinja2` templating  by adding the following `card_mod` snippet to your card:
+
+```css
+# light entity example
+
+- type: light
+  entity: light.01234
+  name: Desk
+  card_mod:
+    style: |
+      ha-card {
+        {% if is_state(config.entity, 'on') %}
+        background-color: var(--cyan-color);
+        {% endif %}
+      }
+```
+
+Then when the entity is on (light in this example) you would see this nice overlay:

+![Theme - State Overlay](docs/theme-state-overlay.png)
+
+> PS: note that state may vary depending on your card. In that case you would just have to adapt `{% if is_state(config.entity, 'on') %}` accordingly.
