    # without needing to edit existing call sites.

    # It might be helpful to normalize this convention with an API
    # anyway as we generally want to use the 8/16 colour defaults
    # as they pick up user terminal customisation properly, whereas
    # going full 256 or 24 bit colour means generic RGB values are likely
    # to look shit on customised terminal backgrounds.
    #
    # This way we get the benefits of *mostly* sticking to the terminal
    # defaults, while extending the range of colours with a few carefully
    # chosen values.
