Not a big fan of case statements?

HostName=${HOSTNAME%%.*}
case $HostName in
  capncrunch) HostColor="\[\033[1;36m\]";; # Bright Cyan
  piglet)     HostColor="\[\033[1;35m\]";; # Bright Purple
  ...
esac

Also, for the record, your quotes are in the wrong place in your [
commands.  You need quotes around "$HostName" to avoid globbing and
word splitting.  You don't need quotes around simple strings like
capncrunch and piglet, unless one of them contains whitespace or
punctuation that's significant to the shell.

The missing quotes around "$HostName" have never mattered because so
far all of your hostnames have been safe.  Maybe that's even a
guarantee -- I'm not sure what characters are actually allowed in a
Linux hostname.  But quoting correctly still a good habit to get into.
