Just for fun,

Code:
/writeini colors.ini list <nickname> <color1-16>

colors.ini
[list]
Nickname1=3
Nickname2=4


Code:
on ^*:text:*:#: {
  if ($readini(colors.ini,list,$nick)) { echo -tlbmf $chan $+(,$ifmatch) $+ ,12 $+ $1- | haltdef }
}


This will allow you to set different colors for different nicknames. The colors are based off of the mirc 16 colors. The "12" is the background color that you can change as well.
