Armenians and Lebanese tend to be slightly lighter because Armenian's have a present chunk of R1b (30%), rivalling and defeating J2 for the countrie's highest paternal marker (25-30% as well.) They're lighter because more J2 I guess saves them from the extremely Arabian/olive-skinned look of the J1 Arabs. I personally noticed that southern middle easterners such as Saudis, Jordanians, Yemenites, Omanites almost always tend to be darker. Ironically they also have quite high J1 levels. There hair is always very black, they're skin very olive; many Lebanese and Armenians could probably pass for Mediterranean Europeans because they have thick black hair but a slightly lighter complexity, probably due to their higher R1a,R1b,J2 levels than Saudis or Iraqis have.
