Preheat the oven to 350 F. In a large bowl, mix together cake mix, eggs, and vegetable oil until smooth. Divide the cookie dough into three bowls. Add blue food coloring to one and red to another.
Take a small amount of each cookie dough and roll together into balls. Place onto a large ungreased baking sheet at least 2-inches apart. Bake for 10-12 minutes.
