From an purely physical point of view darker shades of skin to be prettier. This is possibly because darker tones generally hide imperfections better than lighter tones do.
And if there is a subcultural influence present, of any kind, I wouldn't really care too much about it either. The thing that I foremost look at is how responds to me in the sense of affection, manipulation, understanding, ect. General pros and cons of any person.
A person can be loud and brash, seemingly 'angry', but still be sweet and kind in their own way. What I can't stand however if it's the verbally abusive/manipulative kind. That I won't take from anyone.
