One reporter says hair the color of chestnut , the other golden - but, especially if mostly straight at the top, as described, it would look catch the sun and look quite quite light in the bright midday sun, especially with predominately black haired folks around Him. Jesus and Mary’s ancestor King David was “ruddy” - traditionally interpreted as red-haired. [And another ancestral relation, Esau - brother direct relation Jacob -
Esau means “red”.]. And one witness describes Jesus’ eyes as gray, the other blue - and blue eyes often take both casts. The typical Jewish person we think of has black or very dark brown hair and dark brown eyes, so its understandable to assume that Jesus was like most Jews we think of, but in reality, not all Jewish people have the same coloring. They have variety! And as one witness of Jesus wrote, his less-common Jewish coloring helped him stand out in the crowd - which was a certainly a Grace for the many who were seeking Him in crowds.
I have not read the replies, but I know many will have said, “I don’t care what he looks like”. To me that’s a sort of defensive reply, as in, “I don’t want to spoil it by imagining wrong, so, I’d rather not know.” [editing to add: I mean, they do not want to risk believing an untruth, which is understandable]. And of course, it is not what matters ultimately about any person. But besides being souls we are material beings in a world both physical and spiritual, and Jesus came as a physical being and he did have a particular unique look, as all persons do. I am an artist and I have really wondered. So when I found that above-linked website, it rang true to me. Not only that, it matches the physical description of Jesus and Mary by mystic Maria Valtorta, who wrote of the life of Christ as Jesus mystically showed her, and she described everything she saw, including the physicality of Jesus and Mary, and the disciples, Gamaliel - everyone, as well as showing us, through their interactions and conversations, their vibrant and unique personalities.
Maria Valtorta is a visionary I trust, as do many priests, bishops, cardinals, theologians and cloistered monks and nuns. Finding the above link was a great blessing to me, but it was second to the blessing of stumbling on Valtorta’s Poem of the Man-God. Its thousands of pages have blessed me greatly. Here is my favorite story of many, many favorite and beloved parts of the work, The Adoration of the Shepherds.
It is private revelations so no one is obliged to accept it as inspired by God. I believe it is the gospel fleshed out, and great learned Catholic theologians have studied it extensively and found it completely consistent with Holy Scripture. And as well, non-religious astronomers, historians, and anthropologists also find it miraculously and completely correct. (see this Catholic Monk’s website for amazing detailed articles by learned supporters of Valtorta’s works).
