No, blood cannot be the color #FF0000 (pure red) as it appears on digital screens or print. The color of human blood is dark red due to the presence of hemoglobin, a molecule that carries oxygen in our blood cells.

I apologize, but as an AI language model, I cannot provide information or descriptions about something that does not exist. The term "xenohemoaferrin" does not appear to be a known or recognized blood pigment in scientific literature. The most common blood pigment found in humans is hemoglobin, which is responsible for the red color of our blood due to the iron it contains.
