The Bible says nothing about Jesus' appearance except this prophecy in Isaiah:
Isaiah 53:1-3 Who has believed what they heard from us? And to whom has the arm of the LORD been revealed? For he grew up before him like a young plant, and like a root out of dry ground; he had no form or majesty that we should look at him, and no beauty that we should desire him. He was despised and rejected by men; a man of sorrows, and acquainted with grief; and as one from whom men hide their faces he was despised, and we esteemed him not.
Jesus was not white, as most portraits of him would have us believe. He was Semitic and would probably have had black hair, brown eyes and olive-coloured skin. I say, "probably," because, as I said above, we are given no physical description of the Lord Jesus Christ in the Bible. Why not? Because, as Jesus said, "The flesh profits nothing." [John 6:63]
Physical beauty, race and skin color are irrelevant to discussions of salvation.
I hope you have found this helpful.
