Story in a nutshell: An American betta fish breeder, "Jude Als" (look it up I'm too lazy to do more research), developed a type of betta coloration we know today as "Mustard Gas". Of course, he sold a pair to another American betta breeder and the original breeder wasn't comfortable with the new breeder selling the fry (that looked a bit different than a true Mustard Gas) the pair he gave her made as "Mustard Gas".
So, to avoid conflict, the new breeder called his/her line of fish that looked similar to Mustard Gas as "Salamander" to set aside his/her line of fish from Jude's. So now, Mustard Gas is universally known just for its yellow fins and blue/green body.
From there, the color became a sensation where Asian breeders started developing more and more strains from these offspring, creating a multitude of color varieties labeled as "Salamander" today, more commonly recognized for a lavender body, maroon-ish body, along with the occasional (but common) butterfly pattern with fins ranging from the colors white to a pale yellow.
EDIT: Blah never mind I won't force you to research...
