Love to color

I have no idea how good this app is or isnt. It made me rate it before it would unlock the colors to paint with. I have 4 other coloring books some I like more than others. Well see how this one measures up after I get to use it.
Ok, got a chance to use it and its ok EXCEPT; I like to work with 2 colors @ once (variegated) it makes some cool shadowing. Is there a way to do that and Im missing it? I just downloaded it and colored one pic.
