What surprises me, it is not the pigment, but the almost TOTAL ABSENCE of leptorrhine noses (long and thin). I have counted 5 or 6 of them, on the hundreds of people present here
Most portuguese have flat noses(both,from berid and sudanid influence), then you find people with hooked(armenoid like) and straight nose...
In fact it might even be the easiest way to tell a group of Portuguese from a group of Spaniards. Spanish have a greater amount of "sharp-nosed" people among them. Portugal probably has more Armenoids than Dinarids.
