well I'm a paladin and I went to see that vendor and he didn't even drop it when I killed him... must have ate it before he died.  Guess I'll have to get abused on the AH to get the schematic anytime soon.
I'm on the Draka server, and if there's any Hordeling out there nice enough to contact me (Risukage, of the Tech Warriors), I'll gladly supply you with both the green AND the blue schematics for almost no cost. I'm gonna start buying the damn blue one every time I go to IF just so I can put it on the neutral AH. Please? Show the Alliance a little love and you'll get some back! -Risukage, Draka server, miliary.minstrel@gmail.com
And to answer any questions, the red schematic is sold ONLY in Oggrimar, the blue ONLY in Ironforge (Tinker Town), and the Green is found in both Booty Bay and Ratchet. The fireworks themselves can be bought anywhere, but the schematics...*sigh...*
I checked all over the Anonymous forums and every Neutral and Alliance city within my reach, and I've found that the red schematic is Horde-only, the blue schematic is Alliance-only, and the green is found in Neutral cities. One of the few ways to get the other is through the neutral Auction Houses, unless you've got connections on either side. However, you can still buy any color of the fireworks themselves just about anywhere. The red schematic is found in Oggrimar from Sovik, and the blue schematic is Ironforge in Tinker Town. I've also seen green schematics in Ratchet and Booty Bay, but the BB guy is in a back-door hidden room on the lowest level.
Im on Shadow Council serve and I have setup a hord character to bring schematics form horde shops to gadget if anyone is interested. Will sell some in Ironforge too tho I havent decided on a price. As I get thigns moving Ill see about taking alliance specs over to horde. If anyone interested send word to Hamgar on horde or Rejax on alliance.

I suggest instead of spamming thottbot, you post on your specific realm forum at the wow forums if you want this recipe.
