'man bash' and read about PS1 (the primary bash prompt).
There are hundreds of ways to color output, used for all
sorts of things; a very recent example from my life is at
http://sitaramc.github.com/images/git-completion-plus.png --
every command line in that screenshot is colored in some
way.

As an example, the PS1 I use is:

PS1='\[\e[32m\]\t\[\e30m\] \h:\W \$ \[\e[m\]'
