Skin tone is cool and porcelain-like. Painted areas feature aggressive, thick, physical Impasto Body Paint ({argument name="paint colors" default="Magenta, Red, Orange, Violet"}) with clearly defined, pasty brushstrokes and a high-gloss, wet sheen. A highly saturated Magenta and Violet vertical color streak runs down the right cheek, resembling a stylized colored tear or purposeful paint drip.",
