If you go to Scandinavia/Finland most people are disappointed that not everyone looks like a Nazi poster character. Most people are normal height and have dark(ish) hair, some even have dark eyes.
Apart from all the recent immigrants Sweden does have Gypsies, Jews, Finns and Lapps. Also Swedes, like other Scandinavians and Finns, have some East Asian blood. Russia is much more mixed. There are loads of nonwhite natives in Russia, plus Russians have more nonwhite blood, still people calling Russians Mongoloid Golden Horde etc. are exaggerating. They're pretty white, maybe whiter than 'White Americans' actually.
