We did a Blue Man Group skit with three guys wearing the paint on their faces and the back of their hands for about an hour. It was a weird shade of blue, and some of the guys didn't apply it as evenly, we used blue swim caps to cover their heads. It looked different as it dried on black vs white skin which didn't help. But the point was made, so it is good for a gag type skit, or Halloween, no where near the professional oil based foundtaion shiny blue used by the real Blue Man Group.
