I have been feeling some colored eyeliner lately. It just adds something so different to any look. It adds a kick of fun without being too overboard.
Using my cat eye trick, I applied my liquid liner. I used Nerdrum (the darker blue) and drew the triangle on the outer part of my lid. I filled in this triangle once I was pleased with it.
Using Nietzsche (the periwinkle color) I filled in the inner part of my lid. When reaching the center of your lid, start to lift up and only draw on the top half. This color will not go all the way to the other end of your eye. I stopped about halfway.
