`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.
