From `dir --help`:

> Using color to distinguish file types is disabled both by default and with `--color=never`. With `--color=auto`, `ls` emits color codes only when standard output is connected to a terminal. The `LS_COLORS` environment variable can change the settings. Use the `dircolors` command to set it.
