His skin tone is representative of those who lived in the region at that time. The problem is you don't understand what the scripture is talking about. It is a description of Jesus glorified body.
Revelation 1:14-15 KJV
His head and his hairs were white like wool, as white as snow; and his eyes were as a flame of fire; [15] And his feet like unto fine brass, as if they burned in a furnace; and his voice as the sound of many waters.
Hairs white like wool. Due to His age and His wisdom.
Isaiah 45:21 KJV
Tell ye, and bring them near; yea, let them take counsel together: who hath declared this from ancient time? who hath told it from that time? have not I the Lord ? and there is no God else beside me; a just God and a Saviour; there is none beside me.
Isaiah 46:10 KJV
Declaring the end from the beginning, and from ancient times the things that are not yet done, saying, My counsel shall stand, and I will do all my pleasure:
Daniel 7:9 KJV
I beheld till the thrones were cast down, and the Ancient of days did sit, whose garment was white as snow, and the hair of his head like the pure wool: his throne was like the fiery flame, and his wheels as burning fire.
Eyes like a flame of fire. Nothing hides from the Lord.
Hebrews 4:12 KJV
For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow,
and is a discerner of the thoughts and intents of the heart.
Hebrews 4:13 KJV
Neither is there any creature that is not manifest in his sight: but all things are naked and opened unto the eyes of him with whom we have to do.
Luke 12:2-3 KJV
For there is nothing covered, that shall not be revealed; neither hid, that shall not be known. [3] Therefore whatsoever ye have spoken in darkness shall be heard in the light; and that which ye have spoken in the ear in closets shall be proclaimed upon the housetops.
Feet like burnished bronze. Burnished bronze is white hot as its been heated up. It wasn't cooled down. Which means no impurities.
Ezekiel 1:5-7 KJV
Also out of the midst thereof came the likeness of four living creatures. And this was their appearance; they had the likeness of a man. [6] And every one had four faces, and every one had four wings. [7] And their feet were straight feet; and the sole of their feet was like the sole of a calf's foot: and they sparkled like the colour of burnished brass.
Daniel 10:5-6 KJV
Then I lifted up mine eyes, and looked, and behold a certain man clothed in linen, whose loins were girded with fine gold of Uphaz: [6] His body also was like the beryl, and his face as the appearance of lightning, and his eyes as lamps of fire, and his arms and his feet like in colour to polished brass, and the voice of his words like the voice of a multitude.
Barnes' Notes on the Bible
And his feet like unto fine brass - Compare
Daniel 10:6, "And his arms and his feet like in color to polished brass." See also
Ezekiel 1:7, "and they" (the feet of the living creatures) "sparkled like the color of burnished brass." The word used here - χαλκολιβάνω chalkolibanō - occurs in the New Testament only here and in
Revelation 2:18. It is not found in the Septuagint. The word properly means "white brass" (probably compounded of χαλκός chalkos, brass, and λίβανος libanos, whiteness, from the Hebrew לבן laban, white). Others regard it as from χαλκός chalkos, brass, and λιπαρόν liparon, clear. The metal referred to was undoubtedly a species of brass distinguished for its clearness or whiteness. Brass is a compound metal, composed of copper and zinc. The color varies much according to the different proportions of the various ingredients.
