I always assumed that Purple Dust is Gravity Dust. Its general coloration is black, but it'll take on the color of its user's aura when manifested.

In Ruby's case, it appeared as red and black shots when she switched rounds in the Red Trailer.

For Blake, since her aura is dominantly purple, it takes a dark purple look.
