There's just one problem, Black Dust is currently theoretical, as there's no proof that it exists. There has been passing theories of it being involved with Grimm. But those are speculative.

That said, I'm willing to concede the possibility of Black Dust once its shown. For now, I'm on the belief that Purple Dust is the closest we got to it.
