Weiss: "Dust! Fire! Water! Lightning! Energy!" I think red dust is fire and that powder dust is stronger than crystal dust.

Besides, if you look closely during that scene I was quoting (Ruby meeting Weiss), as Weiss shakes the vial, you can also see some blue and yellow dust mixed in with the red. When Ruby sneezes, it's mostly a fiery explosion, due to there being mostly red dust. But mixed in are bits of ice and lightning, like the blue and yellow dust.
