Maybe the photo is from Niebla, a town in the province of Huelva.
This other would be from the city of Huelva and capital of the province of Huelva.

Do the swarthier types have more North African admixture than the regular looking ones?

^^

In the first photograph, the ones you call the most black are tanned by the sun and all the women have dyed hair. I do not look like North African faces but Iberian faces. I am surprised that you want to confuse a sun tan with a natural color curiously always for Europeans of the South.

I think it is clear that everyone has their own identity and appearance. I do not see the people of North Africa so dark.
