Colorful star tattoos on the back of the ear don't get much attention accept for the guy nibbling on the nape of your neck and spots them only to begin that licking phase. you can make the stars tiny or large it's up to you. I was told that colors come in threes so remember that when you hit the parlor.

My sister had a similar tattoo, well at least in the same area behind her ear. She said it was major pain! When she got the other side done she used a numbing cream she found called Deeveeant Numb. More info here.
