I'm going to need to go back to my dvd to check, but I'm pretty sure the directors commentary mentioned that all semblance can use dust.

And I'm especially sure that they mentioned that ice dust was the one that was going to have the greatest effect on how blake's semblance evolves.

So there's a possibility that semblances have particular dust inclinations.
