`bat` looks good on a dark background by default. However, if your terminal uses a
light background, some themes like `GitHub` or `OneHalfLight` will work better for you.
`bat` automatically picks a fitting theme depending on your terminal's background color.
You can use the `--theme-light` / `--theme-light` options or the `BAT_THEME_DARK` / `BAT_THEME_LIGHT` environment variables
to customize the themes used. This is especially useful if you frequently switch between dark and light mode.
You can also use a custom theme by following the
