Rainbow Cake

I used a half a cap of coloring like in phwarfcat's version, prolly why mine look more pastel like theirs. I also didn't spend much time spreading out the colors, I figured they'd settle in the oven, nope! Also, don't wait a half an hour after making the batter for the dishwasher to wash enough bowls, cause your batter will deflate somewhat and you'll have a denser cake like mine.
