Colour Errors / Warnings / Information in bash script

So I have the following variables defined in /etc/bash.bashrc: RS="\033echo -e "$FRED Red" *at the prompt*, I actually get Red in red on gnome-terminal, but when I execute: #!/bin/bash echo -e "$FRED Red" echo -e "$FYEL Yellow" echo -e "$FGRN Green" I get everything in the default colour even though $TERM is xterm-256color.
