They have already shown that they change colours at a whim - look at the Wind Dust fiasco. One minute it’s green, the next it’s white.

I’m fairly certain that in the Weiss Short for V5, she spinMyrtenaster, it landed on purple, and then she created a black glyph from it. It could be that mining and purifying the dust changes the colour, since powdered Dust is basically Dust+. It’s described as more potent but also more volatile.

Basically, crystals are black and the effects are black, but whatever the SDC does to refine it turns the dust purple when powdered.
