Green skin is cool


I'm sure I'm not the only one who thought She-Hulk was hot, and wouldn't have been as interesting without the green. Same goes for some of Kirk's girls.
So how would you make yourself/other humans green? Yes, you could use body paint or other lame modern methods, but how would you make natural green skin? Should we? Would green skin be an advantage? Disadvantage? New brand of racism? Let's hear some discussion.
