I've heard that before. I don't see why it should matter at all. If you are like and are attracted to a person, that's all that should count IMO, barring other important factors of course, skin color not being one of them.
I think you need to understand that complexion, i.e.,
skin color, while most instantly recognizable because of its visual immediacy, is least prominent of the distinguishing characteristics of the various "races" (human sub-species).
While the population of India consists of a widely diverse ethnic conglomerate, e.g., the
Bagdi caste, the
Banjari, the
Bhat people,
Bengali Hindus, and several others, the complexion of most Indians is comparable to that of Africans, yet they are not Negroes.
The same thing may be said for so-called "White" peoples (Caucasians). E.g., the complexion of a typical blue-eyed, blond-haired, pure Norwegian, Swede, Icelandic, etc., is significantly lighter than that of the recognizably darker skin of the Caucasian Spaniard, Northern Italian, or Greek. Yet all are categorically
White.
So complexion, alone, does not determine one's ethnic grouping. The term, "skin color" has been habitually misused over the years.
