Anyone can imagine Jesus any way they want to, but for what it’s worth, there are plenty of blond and blue eyed people in the Middle East, as can be seen in Lebanon, and Jesus is of David’s lineage, which was supposedly noted for its fairness/redness of hair. So the idea that European depictions are false, but Ethiopian ones are true, or that he looks like this or that modern Jew, are almost all equally unprovable. So, whatever works for you.
I think that he could be this: black to a white racist, white to a black racist, a child to a child rapist, etc.
