CLI apps can detect the background color of the terminal, and determine contrasting colors accordingly.

  They can? Is this a recent thing? I remember wanting to detect the background colour years ago, and not finding any way to do it.

    It's not recent, and most terminals support it. You send an escape sequence to the terminal, and get back a sequence that tells you the exact background color.
