[[gitconfig]]で `delta.features` にプリセットテーマ名を指定する。
```toml
[delta]
features = colibri
```
プリセットテーマは別途 `delta/themes.gitconfig` などから読み込む必要がある。
```toml
[include]
path = PATH/TO/delta/themes.gitconfig
```
`themes.gitconfig` がない場合は、[delta/themes.gitconfig](https://github.com/dandavison/delta/blob/main/themes.gitconfig)の一部を[[gitconfig]]に定義してしまえばよい。
```toml
# 個人的なオススメカスタムテーマ
[delta "weeping-willow"]
# See 'mirthful-willow' for light mode version.
# Heavily inspired by the themes above. Thank you. <3
