I know this is a bit controversial, but the reason why Jesus was depicted as white in much art work is that he probably was:
Consider:
Gen. 25:25 - “And the first came out red, hairy all over like a skin; and she called his name Esau”. This was Jacob / Israel’s twin brother. He has the same genes, so it would make sense these characteristics would show up in his progeny.
1 Samuel (or 1 Kings Septuagint) 16:12 - “And he sent and fetched him: and he was ruddy, with beauty of eyes, and very goodly to behold.” This is the description of David as a lad. Ruddy is taken to mean red, his eyes stood out as unusually striking, just as many red heads of Keltic descent have green or blue eyes.
Jesus’s genealogy is traced back on both his step father’s side (Mathew ch.1) and maybe most importantly his mother’s side (Luke ch.3). They both lead back to David. If his forefathers were obedient they would have only married fellow Israelites and more than likely mostly Judeans (since Judah was divided from the rest of Israel after Solomon’s reign), as an educated hypothesis there was likely a lot of marriages in this family within the royal stock of David as in the case of Joseph and Mary which I believe was no coincidence, there by keeping the blood line pure and unmingled with the people of the nation as was often the case post exile. This detail helps establish the astonishment of Nathaniel when Jesus saw coming on the road and said to him: “See, truly an Israelite in whom there is no deceit.” (John 1:47).
In a round-a-bout way I’m establishing that Jesus was what we may call “white” who probably/possibly had similar features as David.
There was a historical source that I heard, I don’t remember if it was Josephus, Pliney or someone else that described Jesus as having blue eyes. I have not seen it for myself, but perhaps someone else has and can confirm it.
You may also find the video series “100 proofs the Israelites were white” of interest if you wish to do research:

This video covers 10 proofs and is nearly 2 hours, you can find the other videos that cover the rest on the same channel, but I don’t feel like digging it out.
The race subject was not that important to me and I get the sense that the OP was not sincere in his question. I will add that no matter the race, the usual european artist depictions are not accurate in that they show Jesus with a smooth face and a bit on the lean side. As was the custom and part of the Law of Moses, Israelites were to keep a beard. Jesus also worked as a carpenter probably since the time he could pick up a hammer and saw, it would be logical that he had some muscle.
