Hm... so would this mean that blue is solid air/platform/I can't really explain it, red is push and black is pull Glyph/Semblance wise? OK, pretending this information is canon (it's actually pretty smart, though, so wouldn't be surprised if this actually is canon) broadening this theory. So, yes, blue is solid air or however I tried to explain it and red is push and so on. That means that Glyphs are completely not affected or produced by dust, and Weiss' other powers (ice streak, flames etc.) are affected by dust. So that means Glyphs aren't dependant on dust but Weiss still has a reason for actually bothering to make dust chambers for Myrtenaster. OK. That seems good to me.

My brain hurts.
