Regarding Portugal's Pepe, there's no way he's Black. He looks triracial to me, perhaps 1/8 Negro ancestry. An example of what a Brazilian mulatto would look like is Portugal's Jose Bosingwa.
Pepe before he shaved his head had the hair texture of a European or Asian man, not that of a Negro.
pepe is, like most brazilian from the north of brazil, triracial: black, amerindian, and white (but not legit white, they can't tell any white ancestor in their family, like thierry henry for example)
there are no picture of his family because the brazilians don't care about pepe, since he is a bad brazilian player
same for david luiz, he's not a good brazilian player (played in 3rd division in brazil)
but i'm pretty sure that one of his parents looks totally black
The Brazilians have been highly overrated for the last few years and are not nearly as good as during the Ronaldo era. They do not have a single world-class attacker right now. Although Alexander Pato is a solid forward, he has not fully met what's been expected of him. In the midfield, the Brazilians have nothing: both Lucas Leiva and Ramires are only above-average players, and they're not good enough to shine the boots of the Spanish players. It's only in defense where Brazil have truly world-class talent in Thiago Silva and Daniel Alves.
a new middle fielder is oscar from internacional, and previously sao paulo
i saw him play for internacional, he's very good
a little bit skinny for european football though
he's white
pato is, when not injuried, the best player in the world, better than messi and diego forlan, and you probably know how much i like diego forlan
dani alves is overrated i believe, barcelona could do without him (they are trying to sell him right now)
