+### Color Picker
+
 Enable the color picker setting to change a color using a color picker in live preview mode. Note that the color picker does not support opacity, and will only let you select from sRGB colors. It will attempt to preserve the existing format you have written, as well as any existing opacity.
 
+### Custom CSS
+
+Customize the inlays by targeting the `.css-color-inlay` class. For example, you can make them circular with the following snippet:
+
+```css
+.css-color-inlay {
+  border-radius: 100px;
+}
+```
