This is not a tutorial or anything and most of this can be found
googling, but this is my prompt:
PS1='^[]0;$USER@${HOST} ${PWD##*/}^G^M^[[0;32m[$USER@${HOST} ${PWD##*/}]$^[[m '

Note that the ^[ and ^G in the prompt string are single characters for
ESC and BEL (can be entered in emacs using C-q ESC and C-q C-g).  The
^M is a carriage return (C-q C-m in emacs), and needs to be used after
other escape characters in the prompt, so ksh can determine the screen
width properly.  I couldn't figure out a way to enter these control
characters with vi, but I didn't try too terribly hard either.  The
${PWD##*/} is a ksh construct to get the basename of the directory you
are in.

This part sets the title: 
^[]0;$USER@${HOST} ${PWD##*/}^G^M

This part set the prompt (with color): 
^[[0;32m[$USER@${HOST} ${PWD##*/}]$^[[m 


So a no frills color prompt without the title might be:
PS1='^[[0;32m[$USER@${HOST} ${PWD##*/}]$^[[m '
