Coloration
Judeans of the 1st century were biologically closest to Iraqi Jews. When it comes to coloration in this regard it means olive-brown skin, brown eyes, dark-brown or black hair. Jesus would have been a man that resembled a man of Middle Eastern appearance. This was studied in relation to skeletons of that time and remains found of Judeans. The coloration of Jesus is thus, not the white figure we expect and are usually exposed to.
Height
With regards to height, the average height for males during this time is approximately 166cm, being 5 ft 5. He was not super tall but actually rather short if you think about it. However, this at the time was the norm for men in this region. Jesus is thus interpreted as a man of Middle Eastern appearance with a scruffy yet short beard, he wore basic attire being a knee-length tunic and most likely an undied mantle.
