Usually blue. But the best way to tell is if, say, you are playing a game and colors are constantly rotating on your screen. If a pixel does not change colors as they rotate, it's most likely dead.
 
Pixels can be dead or stuck, based on transistor malfunctions. If it's dead, it'll be a little black dot. If it's stuck it would be a bright red, or blue, or green dot.

Try this.

In the case that it's stuck, is there anything you can do to help fix that? I've had a stuck pixel on my 20" display since I got it over a year ago.. and it's really annoying.

I've heard of massaging it.. laying it on it's face for a couple hours. Obviously none of that worked..

no massaging involves you rubbing the dead/stuck pixel with somethinglike a pencil eraser..

get one of those programs that will turn your entire display black/white/green/blue/red so you can check.
and you can usually see it with your eye, no need for a magnifying glass.

Yeah yeah, that's what I meant.

Does that work? I tried my finger... which in hindsight seems a little lame.
 
I took a screen shot of a dead pixel.
