Sorry the picture is a little blurry. (I have few like this to be posted.) I took this before I found out about the macro setting on my camera.The nail polish colours may seem different, but it is just different lighting.
The colours I used were Avon's Pastel Pink, Cotton Candy and Viva Pink. I really like the look of this and I think the nails turned out pretty. The Cotton Candy nail polish is rather sheer, so doesn't show up well in the gradient.
If you are interested in doing this nail design, I followed this tutorial:
