Cinder seemed to be using bright orange Dust, though, and Ruby saying that she didn't think Cinder's Semblance was glass was the writers' way of telling her that her Semblance doesn't have a connection with the glass.

I'm not sure why there would be glass Dust anyway, to be honest. That would seem a little weird.

As for making Dust be a matching color, I still don't think they'd change what color the Dust is just for that character. Monty had said that he was originally going to make all of the Dust in Weiss' rapier be red but still do different things because it looked good with her color scheme, whereas a rainbow would clash with it. However, he realized that it would be much nicer and easier for the audience if Dust was color coded regardless of who was using it so that we would be able to more easily understand what type they're using.

It would make sense for them to do it the other way around, though: Decide that a character should be the kind of person to use a certain type of Dust and then design their appearance, or at least their clothes, based around that Dust's color so that it would look good.
