# Dark mode
You can set the dark mode globally for all Vueless components.
export default {
colorMode: "dark", /* default -> auto */
};
### Possible color mode values:
* `dark`: Enables dark mode. Adds the class `vl-dark` to the `` tag.
* `light`: Disables dark mode. Adds the class `vl-light` to the `` tag.
* `auto` (default): Adapts to the user’s system settings for dark mode. Automatically adds the appropriate class (`vl-dark` or `vl-light`) to the `` tag based on the user’s preference.
