There was a stripper I knew (know) who had a dark but smooth complexion. I mean just perfect. No blemishes or anything It was like a clean, evenly baked bronze. I used to call her "Pretty Chocolate" every time I saw her. I'd be like, "Heyyy, Pretty Chocolate", and she would beam those pearly whites from ear to ear.
That's what I'd go with. Maybe spell it with an 'i' at the end.
