It makes sense, to be honest. Women are on average, in every ethnic group in the world, the lighter ones. It's human sexual dimorphism. Something about male sex hormones makes men produce more pigment on average. This also weirdly tends to correlate with male and female sexual selection among humans where you notice that males, on average, will prefer a woman of their group who is somewhat lighter than them whereas women will, on average, prefer men who are darker or find darker features more attractive. Can't find them off the top of my head but there have been several studies showing this. There is some real truth to the "fair maiden" trope.
