It's strange that you used shell builtins for the $- check but not
for this check.

read -r Hue _ < /var/local/lib/myhosts/colours/"$HOSTNAME"
if [[ $Hue = [0-9] ]]; then

Or if you happen to use the other fields of that file later in the script,
then change the read command to store all 3 fields in shell variables.
