If you're talking about your bash command prompt then maybe http://tldp.org/HOWTO/Bash-Prompt-HOWTO/x329.html will help. If you're talking about within your editor then that would be editor specific but for vim you need to make sure that the vim-enhanced package is installed and then you need to edit ~/.vimrc and make sure it contains the line "syntax on". If you are root then that user lacks an alias to point the 'vi' command to /usr/bin/vim so syntax highlighting does not work so you need to alias vi=/usr/bin/vim' in one of your bash startup files.
