# This script will take an HTML compatible hex colour string and turn it into
# a terminal sequence for true colour and other formats which best approximate
# its colour value.
#
# After that, we can map a few other special named symbols. The idea is to
# permit shell variables such as `aaffcc bold italic` to indicate what you
# want a format to look like.
#
# TODO: Update the script to allow for `bg:ff00ff` style descriptions, instead
# of positional.
