Europeans really have no point of reference in terms of the appearance of the Ashkenazim. You really should stop drawing conclusions from Jews in American media, many of whom are admixed.
I've worked amongst them for decades now, and draw most of my closest friends from them, and not one of those friends has either fair hair or blue eyes, and nor does anyone in their families. Nor does anyone in the family of my husband's partner, an Orthodox Jew whose wife's family were Hasidim in Europe, have fair hair or blue eyes out of the seeming hundreds who attended his daughter's wedding.
Are there some 100% Ashkenazim who have fair hair and eyes? Yes, there are. There are some Campanians who have fair hair and eyes too, but they're the minority in both cases.
What you have to understand is that the Hasidic men, who are the easiest to identify, spend every waking hour indoors studying the Talmud, so they look very pale. Most Southern Italians who never went outside would also have that pale olive skin. However, most of them are religious not about God, but about getting the best tan possible.
You do occasionally get a red head, which makes sense, since recessive genes are bound to come out in such inbred populations.

You guys have been listening to people from theapricity for too long.
