Sift together the flour, baking powder, and baking soda.

Beat 3/4 cup plus 2 tablespoons butter, milk, sugar, egg whites, and vanilla extract in a large bowl with an electric mixer until smooth. Stir in flour mixture and mix until just combined.

Divide cake batter evenly between 6 bowls. Mix in different food coloring to each bowl, creating 6 different colored batters. Start with just 1 to 2 drops of food coloring in each bowl, then mix; you can always add more.

Bake each cake in the preheated oven, until a toothpick inserted in the center comes out clean, 15 to 20 minutes. Set aside to cool.
