I mixed yellow and red Vibrance micas (looks more like a mauve to me) for the copper, and green & blue Vibrance for the teal-ish blue color, from Nurture Soap Supplies. It was more or less equal amounts of each.
I can't wait to try another one, I hope I have the time tomorrow!!
I have the Vibrance micas..but not all of them..missing the yellow and green..I'll remember that because those are some awesome colors
