I'v made a recent assumption that orange and cyan are the synthesized, enhanced variants of fire and ice dust respectively, with emphasis on attack empowerment for orange, and defense empowerment for cyan.

The former is an assumption, the latter is based on your examples above.

As for stone, I'm gonna speculate that it's our first example of combining dust; via mixing ice with lava. Resulting in an igneous-esque stone statue of Blake. But that's just me using Minecraft logic.

Purple Dust is likely the Gravity Dust that Monty mentioned before. Its outline appears to be the key color of one's aura. (Ruby's gravity dust has a red outline;Blake's has a purple outline)

Most of these are semi-old notes that I've made, so feel free to refute them.
