Сетих се да је и Кун код наших људи приметио да је брада често доста светлија од косе. Помињу се управо ти риђи тонови.

The Serbs are darker in pigmentation than either the Slovenes or the Croatians; 45 per cent of eyes are pure brown (Martin #2-4), as against 20 per cent which are pure or nearly pure light. Over 55 per cent have black or dark brown hair, while light browns and blonds come to less than 10 per cent.
The beards are, of course, often lighter than the head hair. The skin is brunet-white or light-brown in at least a third of the total. It is unlikely that the prevalence of brunet pigmentation among the Serbs came from a Slavic source, and as we shall presently see, the high incidence of dark eyes can hardly be called Dinaric. By elimination we must suppose that the Serbs, in their sojourn in northern Macedonia. accumulated a strong brunet tendency.

The Montenegrins are prevailingly dark brown in head hair color; in Old Montenegro some 45 per cent of adult males belong to this class, while 20 per cent are medium brown, and 26 per cent auburn, or brown with a perceptible reddish tinge. The tribesmen of Brda and the northern border are somewhat darker, and show less rufosity.
The beards are much lighter than the head hair; among Old Montenegrins 43 per cent are reddish brown, and 8 per cent contain a pure red element; only 17 per cent are dark brown. In Brda golden-brown beards are extremely common, as frequent as 39 per cent; in the northern border tribes, 24 per cent. The rufosity of the Montenegrins, and their tendency to golden blondism, is not only extreme, but is particularly unusual for this part of Europe. It will be recalled that the Serbians, traditionally close relatives of the Montenegrins, are much darker haired, and that the Slavs in general, when blond, favor the ash-blond side of the scale, being almost entirely deficient in rufosity.
