You can sorta see the purple trying to come through but the blue is overpowering enough that the purple is made irrelevant. The bright blue shimmer is the real star of this polish and even though it's not a duochrome I didn't mind so much because of how startlingly pretty this looked. Application was alright and it covered in two coats. Next time I'll probably add a third coat just to get the ultimate full shimmer effect.
But so purrty, right?!
