Alright so I know that Hal Jordan has been a green lantern *The greatest Green Lantern*, and during the "Rage of the Red Lanterns" Part 3 Hal became a red lantern, and then in the same book the blue lanterns wanted Hal to lead them, and he also received a blue lantern ring which he then had the blue lantern uniform on. 

So my question is this:

Is Hal Jordan the first tri-lantern????
     I mean seriously a green ring, blue ring, and he was or is *not sure now* a red lantern.

I would have to say that it would have to be either Kyle Rayner or Hal Jordan. 

I would say Kyle since he is a graphic artist and when one thinks of super hero secret identies you certainly wouldn't think of a graphic artist. 

Then there is Hal Jordan.  Yes he is ex-Air Force pilot,  but still he isn't what one would look at and just come up and say wow I can tell your a super hero.
