Actually, Weiss' words are "What are you, braindead? Dust! Fire! Water! Lightning! Energy!" in episode 2. That's why I thought blue should be water.

As for #3, I know that white is all the colors combined together on the color wheel. I was just wondering why you need white Dust (which makes you stronger) in a fight when you already have red Dust to make you stronger. Now that you mention it, the armor did shatter like glass after burning with white fire, so now I can see how different elements are combining together.

For #5, I had thought that Glynda was controlling some other kind of Dust and that the shards were glowing purple because of her specific kind of "Dust-control" technology. (Like those violet circles.)
