The Color Is Dull
The evidence showed that Jesus did not wear that full-length cloak or robe like those upper-class people who were living in that era. The Messiah was wearing a knee-length robe like the other average men. However, would the color of his robe be comparable to the images that we could see in our era? Investigations showed that in that era, there were no methods to whiten the color of the fabric. It means it would be impossible to make the color of the savior robe into white. Most tunics in that period were created from the material called plain wool. In the Bible, statements were telling us that the clothes he was wearing would be dye in white and shiny color when He became a divine being.
Decorative Elements
There were additional features from the illustration showing Christ was wearing a blueish cape or a veil dressed over the robe. However, why did His robe or mask was colored a different shade of blue? There could be a meaning of why it was portrayed in a color of blue. Historians had no explanation about the color of his clothes. They even thought that it has no meaning at all.
