Actually the difference and the unconscious representation is interesting. Pale would typically indicate 'yin-ness', or indeed, aloofness, a kind of divorce from the overly physical. Tanned *can* indicate the opposite, gravitation towards the overt and the physical. And people tend to be imbalanced, so people tend to be too much of the one, not enough of the other. But anyway, I generally notice that people seem to gravitate towards their 'own kind'. Within reason of course, opposites to attract to some extent, and help balance out character weaknesses. Anyway, in the past I liked paler girls more. Overall, pale girls are usually my preference, so long as it's a more balanced look.
