Blackberry mica is a sultry dark purple that has flashes of reddish gold throughout. This color is multifaceted and strikingly beautiful. As with most dark purples, this color can be a bit tricky in cold process soaps. At times you may get a rich amethyst color, and other times it may turn smoky gray. We suggest testing this in your recipe in making CP soap to see how it works for you. This color is stunning in melt and pour soap!
