Forums mIRC Help How to get nick colors working?

The help file says about nick colors:
"The Nick colors section allows you to assign colors to nicknames, which are then highlighted with their assigned colors in the channel nicknames list, and in any messages that those nicks send to channel or query windows."

So if I want to have "Bob"'s name in red I could do that? How?

I open the nick colors window, click enable nick colors, click add, chose a color, and in "nick or address" i enter "Bob" click ok... and nothing happens?

Bob is still black on white.

So what am i doing wrong?
