Lush Foundation?!

So I came across the new Lush color suppliment online. Since I'm not too sure what my color would be I picked up a container at Universal City Walk on my way to Halloween Horror Nights. I've tried it and I la-ove it! It only comes in I believe 4 different colors and I got 'dark yellow'. This color naturally would'nt be my exact face color BUT I mix it with my face lotion to use as a full coverage tinted moisterizer.
