The following two paintings are said to be the work of a Sienese painter named Barna da (or Berna di) Siena. They date from the 14th century.

This next one doesn't so much show a red-haired Christ. It's more of a haloed, illuminated Christ. However, I share it as it illustrates quite neatly the way the halo of light associated with saints and other religious figures seems to lift hair towards a blond or fiery shade. Perhaps explaining the overlaps between red hair and halos I've mentioned on this blog before.
The blood orange was considered to be a symbol of Christ. The word orange is cognate with words like or (French), oro (Spanish) and aurum (Latin) meaning gold. Which in turn are cognate with words like aura.
The painting is titled Going Down to Gethsemane and is by the German-American artist Johannes Adam Simon Oertel. It dates from 1898.

Finally, this one isn't Jesus, but it does look very Jesus-like. It shows Olaf II, King of Norway, later St. Olaf. It's from a stained glass window in Ålesund Church, Norway.
