white is now wind (but what was it before Volume 3?), and purple wouldn't make sense for earth (plus the black-and-purple energy that came from one of Blake's clones). This is why I originally thought white was earth, as odd as that seemed, since it was literally the only color in Blake's clip that could've made the rock clone.

We know Wind was green way back in Volume 2. White is literally the only color left that could be Earth/Stone. I'm assuming they went with white for stone because some stones can be white-gray.

I feel like sometime in Volume 3 they realized how confusing it would be, so they made the switch. White is now wind. And I would bet Green is now earth/stone. It just makes way more sense, color-wise.

I really do think purple dust is gravity dust. Which might explain why we've never seen Weiss use purple dust. She hasn't had a reason to. Yet.
