Why has jesus often been depicted with long brown hair and blue eyes?

Historical fact: Under pope Alexander IV forced the image of his son who was concived through fornication. (his son would later become a homosexual) the pope was a mass murderer and many many other things... ontop of that in 1490 he had the image of his son forced upon all churches so that he would be seen as God (his son name was Cesare Borgia) the true image of christ is a black man with white wooly hair (see Daniel 10 and Revelations 1:12-14)
