In my observation, some variation of brown is most common (anywhere from to very dark) with darker shades of eye more of the norm. However, I've seen them anywhere from true blond/blue eyed all the way through black hair/dark brown eyes. The latter is relatively uncommon. In Moscow, you cannot much distinguish them from any other given Russian. Of course, Moscow has quite a variety of ethnicities wandering around but it would be rather odd to confuse a Chechen for, say, one of the Central Asian ethnic Turkomans.

The Caucasus are basically a melting pot for a number of different ethnic strains. Not just Caucasian (Georgians, Chechens, etc.), but Iranic (like the Sarmatians and Western Scythians-nearest descendants probably the Ossetians), and others. I wouldn't be surprised if the blond hair/blue eye combo was the result of Iranic blood.

Unless maybe you're an anthropologist or ethnographer who's been trained to differentiate between the various specific racial types.
