Any dust can be used by any person if they are skilled enough and know how to control it.

We know that natural dust comes in four core colors, and it has been shown in WoR that the colors are red, blue, yellow, and green. We do not know how more advanced types are created, just that it can be done.

Presumably the natural varieties can be purchased at any shop, while some pre mixed advanced forms would also be available, and those skilled in the use of dust can likely use the core types to synthesize advanced mixtures of their own devise.

Dust can be used to AUGMENT semblances, or be used in combination with raw aura for 'spells' but it is not the sole power source for them.
