Shalam!
Actually the bible did give a color.
Rev 1:13 And in the midst of the seven candlesticks one like unto the Son of man, clothed with a garment down to the foot, and girt about the paps with a golden girdle.
Rev 1:14 His head and his hairs were white like wool, as white as snow; and his eyes were as a flame of fire;
Rev 1:15 And his feet like unto fine brass, as if they burned in a furnace; and his voice as the sound of many waters. [King James Version] brass would be like a brownish color right?
Dan 7:8 I considered the horns, and, behold, there came up among them another little horn, before whom there were three of the first horns plucked up by the roots: and, behold, in this horn were eyes like the eyes of man, and a mouth speaking great things.
Dan 7:9 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.
Dan 7:10 A fiery stream issued and came forth from before him: thousand thousands ministered unto him, and ten thousand times ten thousand stood before him: the judgment was set, and the books were opened. [King james]
What people in the earth today have wooly hair? The so-called African Americans. You should read more of my notes. Have a blessed day! Shalam
