In all honesty, with the exception of blue = ice, most of these are pretty ambiguous.

I think that red = repulsion, and maybe she has another red chamber there that = fire. Also, Violet casts a binding spell on her enemy. White increases the strength of the blade. And maaaaayyyybe yellow = a disarming spell over the blade. That's just me grasping at straws, though.

Here's my theory regarding dust:

Personally, I think that a lot of her abilities come from herself. Whenever she does something that involved an air step, or a rune that appears in the ground or wherever, that's when she's using dust in conjunction with her own body. I think that dust use is partially mentally controlled, at least, when it's not being harnessed through a weapon, because it's been stated that you don't need a weapon to use dust effectively. I think that the "spells" that strictly affect her sword are the revolving chambers of dust in Myrtnaster. But when she uses things like her airstep and stuff like that, she's using dust in conjunction with her mental powers. I think with the right dust, you can mentally command it to do something, without the use of a weapon, and that's what she does when she does things like air steps, slingshooting Ruby through the air, and giving her platforms to run up the cliff with. Those have nothing to do with Myrtnaster, that's all Weiss.

But that's just me. There's still been pretty much no clear explaination as to how dust works.
