Blue smoke?

[RanchStroke]

What does blue smoke mean? Sometimes when I start my 06 up at the first stop sign I see some blue smoke, but not enough to smoke somebody out. Do I not let it warm up enough?

sounds like cold smoke, mine did that before but it ended up bein head gaskets and it would blow blue first thing in the mornin cause antifreeze would be wet in my exhaust and then the heat would dry it out and blow blue smoke
