I'm typically drawn to blue and green polishes more than anything. Although I usually love them right off the bat, I don't think I'm biased in loving this polish. It is truly an amazing holo, and the color is just amazing.
For some reason, I'm used to seeing holographic polishes in lighter colors. Milani, Nubar, Layla - some of them make darker silvers, almost black, but the other colors really aren't all too rich. This blue is super rich and royal looking.
Sea Spray applied nicely with no streaks and no problems. This is only two coats of it, topped with a coat of Out the Door. It's very pigmented, so it isn't too sheer, but it is also somewhat of a jelly, so you get that added depth and glossy look to it.
I am seriously just stunned by this polish. It is gorgeous! I love how it is a deep, rich holo with some depth - definitely my kind of polish.
