Actually, I'm sure that the Dust Cinder uses is red, since she uses fire, and red Dust is fire. The red Dust crystal Roman took in v1e1 was called Burn, and in v1e2, when Ruby sneezed on clouds of red, blue, and yellow Dust, there was a fiery explosion with ice and electricity in it.

As for purple Dust, I have no idea what it does, so Glynda may actually be using purple. That would mean the only places we've seen purple Dust are Glynda's cape and a slot in Myrtenaster, though Weiss has yet to use it. Purple could be a fairly uncommon type of Dust. If it is, I wonder why it's uncommon.

Is it hard to mix the colors that are required for it? Ordinarily, one would assume the two colors that combine to make purple Dust are red and blue, but we don't know if mixing Dust causes it to undergo a "chemical" reaction. I mean the basic sense of the term chemical reaction, wherein the two reactants go through a change that forms an entirely new substance, which is what it sounds like combining Dust does. Chemical reactions can even change the substance's state of matter or color. So, for all we know, purple Dust could be a mix of yellow and blue Dust or blue and green Dust or whatever.
