Nice theory, but i cant agree with all. We dont have info to assume Dust is more powerful in powder state, i think humans refine it to use it in other ways, like to make mixtures or other compost.

Dust is basically energy, and in my opinion, energies from their world. Fire energy made Orange Dust, and thunder energy made the yellow one, and so go on ....

If some of Dust types use the forces of Nature: Orange - Fire, Blue - Water, Light Blue - Ice, Yellow - Thunder, maybe Green is Wind, maybe is just cinematics but Weiss disarmed the Metal Golem with a strong energy current.

Grey and violet is a real mystery but i think White Dust, is the neutral and pure energy not associated with the others colors effects
