You can use these themes by replacing the `[theme]` section of your [config](https://github.com/makeworld-the-better-one/amfora/wiki/Configuration) with their contents. Some themes won't display properly on terminals that do not have truecolor support.
## Amfora
This is the original Amfora theme we all know and love. From v1.9.0 and onwards, the user's terminal theme is used by default. Use this theme to restore the original Amfora look.
