Make the cakes:

  1. Preheat oven to 350 degrees. Grease three 7-inch cake pans (or two 9-inch cake pans) and line the bottoms with parchment circles. Sift together flour, baking powder, and salt; set aside. Whisk together egg whites, buttermilk, oil, sugar and vanilla in a separate bowl; set aside.
  2. Add dry ingredients to wet ingredients in three additions; beat until smooth on medium-low speed after each addition.
  3. Divide batter between three bowls. Tint one bowl with neon purple food color and mix until a vivid color is achieved. In a second bowl add equal additions of classic blue and green gel food color; mix until a vivid turquoise color is achieved. In a third bowl tint the batter with bold dark blue food color; mix until well combined. Place large spoonsful of each color batter in the pans, alternating them often so that the colors are well varied. Use a skewer to swirl and marble the batter. Bake the cakes 350 for 25 to 30 minutes, or until a toothpick tester inserted in the centers come out clean. Let cool slightly in pan, then turn out to cool completely. Level each cake with a serrated knife or cake leveler.
