I got this idea from my friend Andy (from TK!) and she got the idea from a book called Hello, Cupcake! I made mini cupcakes using a box mix of Funfetti. Then I took store-bought vanilla frosting and divided it into 4 bowls. I tinted the frostings using blue, red, yellow, and green food coloring (liquid). I popped the bowl of frosting in the microwave for about 6-8 seconds and then dipped the cupcakes in the frosting.
