These are all home brew. I'll put a small description with each one.
Purple home brew colored with mica powder from Coastal Scents and some pearl color liquid from CastenCraft.
Green home brew colored with mica powder from Coastal Scents and some pearl color liquid from CastenCraft.
Blue home brew colored with blue mica powder from CS and some glitter type powder thrown in.
Hope these examples help you out.
