This color is so pretty. Rainbow Honey describes this best herself:
Mare of the Moon was inspired by Princess Luna; A deep and mysterious indigo polish with a violet color shift and a sprinkling of silver moon crescents and holographic glitters.
The formula was great. A little thick, but really easy to apply and I didn't have to fish around for any of the moons to come out. I used 3 coats, on the first coat I didn't get any moons, but on the second and third they came out easily, which is actually better so they don't get buried under the polish and can be seen. This picture was taken during a brief moment that the sun was shining, you can see the moons, and a bit of that color shift too!
