As mentioned, the cinny/black pastel supers are likely to have issues. If you just want one as a pet it's not impossible to find one without issues but I wouldn't purposely breed for your own. I have hatched a bunch of Sumas and they're a really dark brown on their own but you can add ghi or a few other genes to them to make them closer to a black color which is my plan. Here are a few of my het pied sumas. They're a cool silvery black before first shed.
