I chose to go for more of a pinky background and to use the blues as the hair and highlights.
I used Collection 2000 Sugared Almond as the background colour and then a mixture of Barry M Strawberry Ice Cream, American Apparel Neon Yellow and Gosh Spot On! Pink. I then used white acrylic paint for the unicorn and star nails and various shades of grey for the outlining and shadows on the unicorn. I then used Barry M Blueberry Ice Cream, Mint Green and Rimmel Aqua Cool all one their own and mixed with Barry M Matt White to create the hair and the nose on the unicorn. I then added some acrylic glitter paint on the star and unicorn nails os that it could be watered down so it wasn't full of glitter. The rainbow nails were down with pink, yellow and green acrylic paint simply so that I could blend them to make them look more like the rainbows on the top.
