B5 has a red dragon. There's debatable merit of the module but there it is.
B3 has a white one iirc. Its been a while.
The Black Wyrm of Brandonsford has a black one presumably.
Curse of The Curse of Cragbridge (the S&W version) has a not! dragon that's pretty great. I just subbed in a dragon when I ran it, it fit with the weird knightly tragedy of the module.
