Same in Indonesia G-tone. Darker skin is associated with outdoor work, therefore lower class. It's not strictly a "race" thing. Paler skin is associated with beauty for women. interesting it then becomes chicken and egg, if you work outside you get darker skin and are therefore not "suitable" for other employment.
Foreign guys who come to Indoneesia tend to go for exotic looking girls, so they tend to go darker, or at least they don't care. Indonesian locals don't understand this as they consider darker to be "ugly".
