Contrasts of colors. I love to combine bright yet very different colors together. I found really old eye pencil that had two sides - one in pink color and other in green, that's how I thought of idea to mix these two colors. To add something even cooler, I put pink in waterline. I was so happy with the look, it actually gives me 80's makeup feels. When playing with makeup, my favorite thing to do - create colorful looks; and as I am writing this I want to create something colorful so badly!
