Swarthy Serbs?

[Decius]

By saying they are darker than Serbs or that they breed with gypsies?

They didnt fuck with gypsies there no genetic proof. They are on par in lightness with Serbs

Depends on the region. Serbia is a very vertically stretched nation, so the top of the country might look more Central European, while the bottom parts near Kosovo and Macedonia have a more Mediterranean-like appearance. Every Serb I've met though isn't particularly dark-complexioned, but had pitch black eyes.
