This is a character from Farscape, played by Virginia Hey. All I really need to say is that blue can really be a beautiful color. She is a Delvian. Certain episodes have presented various color schemes. I particularly remember a red Delvian.
Zhaan is a 10th level Pa'u in the religion of the goddess that she adheres to. She has immense powers, especially of the mental variety, and is skilled chemist.
Oh, and she is a sentient plant - this is most emphasized when she is exposed directly to solar radiation because she finds it sexually stimulating.
The makeup for this role must be intense to put on all the time, but always looks great.
