It's depending from person to person from both genders which preference they've. Some prefer pale, some prefer tan or brown and some prefer both.
I've a preference for tan or a bit brown skin, but I thinks most skin tones are fine as long the skin is clear, healthy looking and I've a preference for freckle free skin.
I've always had a preference for dark looking people and for the South-European, Asian, Middle-eastern and South-American look. Tan and brown skin often hides blemishes, acne/pimples, small scars and other small details better than pale skin making the skin often appear clearer. Natural brown skin (not the fake orange tans) often appears as lesser pinkish than pale skin too making the person look lesser exhausted or sun burnt.
