-### 2. CSS Variables
+### 2. Theming with CSS
 
-Override CSS variables in your global styles for theme customization:
+The library uses CSS modules with predictable class names (prefixed with `rc_`). While the internal Sass variables don't support CSS custom properties due to color manipulation functions, you can still customize the appearance through CSS overrides:
 
 ```css
