## Customizing the look of Gitea
The default built-in themes are `gitea` (light) and `arc-green` (dark).
The default built-in themes are `gitea` (light), `arc-green` (dark), and `auto` (chooses light or dark depending on operating system settings).
The default theme can be changed via `DEFAULT_THEME` in the [ui](https://docs.gitea.io/en-us/config-cheat-sheet/#ui-ui) section of `app.ini`.
Gitea also has support for user themes, which means every user can select which theme should be used.

Gitea supports three official themes right now, `gitea` (light), `arc-green` (dark), and `auto` (automatically switches between the previous two depending on operating system settings).
To add your own theme, currently the only way is to provide a complete theme (not just color overrides)
As an example, let's say our theme is `arc-blue` (this is a real theme, and can be found [in this issue](https://github.com/go-gitea/gitea/issues/6011))
