Auto-color terminal background to avoid ssh production oopsiedaisies

colorterm.sh

#!/bin/bash
#
# Based almost entirely on Bryan Gilbert's solution: 
# http://bryangilbert.com/post/etc/term/dynamic-ssh-terminal-background-colors/
#
# Sets terminal screen to color based on keywords or hex code (no #, for some reason that breaks)
#
# For SSH magic, add following to ~/.zshrc: 
#
: <<'END_COMMENT'
