Is a black pastel and a cinnamon pastel them same thing? I have read that they both produce pewters (and someone said 'produced black pewters')

I know there are several other morphs that are like this, have different names depending on the breeders....but I can't think of them at the moment. I'm trying to compile a list of what makes what designer morph, and if anyone can remember any of these other names, it would be helpful! ^_^
