+### Customizing styles
+
+Excalidraw is using CSS variables to style certain components. To override them, you should set your own on the `.excalidraw` and `.excalidraw.theme--dark` (for dark mode variables) selectors.
+
+Make sure the selector has higher specificity, e.g. by prefixing it with your app's selector:
+
+```css
+.your-app .excalidraw {
+  --color-primary: red;
+}
+.your-app .excalidraw.theme--dark {
+  --color-primary: pink;
+}
+```
+
+Most notably, you can customize the primary colors, by overriding these variables:
+
+- `--color-primary`
+- `--color-primary-darker`
