printf '\33]11;%s\007' "[$CONN_OPACITY]$CONN_BGCOLOR"

function usage() {
  echo
  echo "tglow: set terminal background and opacity"
  echo
  echo "    usage: tglow 30 green"
  echo "           tglow 95 \"#333000\""
  echo
  exit 1
}

if [[ -z "$1" ]] || [[ -z "${2+x}" ]]; then
  usage
fi

printf '\33]11;%s\007' "[$1]$2"
