My grandfather (100% Norwegian) had olive skin, black hair and dark brown eyes. My dad figured he had the blood of some Mediterranian slave girl that the Vikings had brought home.
Until he visited distant relatives up in northern Norway - Lapland. Pretty much tall, skinny Eskimos! (Still lived part-time in their Reindeer hide huts herding Reindeer.)
Netflix could have told them that most vikings were black.
