When I looked at this in the bottle, I thought, "hmm, a less sparkly version of Ink", but I was wrong. In the bottle Russian Navy has a strong purple cast and doesn't seem very blue ... I was wondering why it was called NAVY. haha. :D
But once I put it on, the purple faded to the background and the glowy blue came out in full force. Lovely! :) This color is sophisticated and hot. Awesome.
I could have gotten away with 2 coats, but I used 3 anyways. As with all dark colors, the 3rd coat made it that much closer to black, so if you're trying to stay away from a blackened blue, use 2 coats.
