I used OPIs "Lincoln Park After Dark-Matte" as the base and then used tape and put china glaze's "pink voltage (neon)" Then did the skinny silver sparkle.
This technique is called water marble nails. What you have to do is paint a base color then pick colors that you would like to be over the base. I will give you an example from youtube. Thought this was a great video so here ya go: http://www.youtube.com/watch?v=8Viul29n3YM
