Unfortunately I was unable to snap a picture before some damage occurred. Sorry for the chips.
For these nails I used three colors:
From left to right we have Pure Ice: Superstar, Avon: Splendid Blue and VS Beauty Rush: 9CN
To do this, I started by painting my nails white. Once the layer of white was dry I used pieces of tape and created a diagonal line as shown below and painted my nails with the blue color. Once that layer had fully dried I used more tape to create another diagonal, leaving a strip of white, and this time used the yellow.
