What Color Is Pokemon Blood?

[♣Gawain♣]

Red. Simple, because Pokemon lived in an oxygen based planet(which is "Earth"), they should have hemoglobin to acquire red coloring on their blood.

Except for certain Steel-types that looked like robots which they can't bleed because they're mechanical based.

 

[Vulpes bicaudata]

Even among species that actually HAVE blood, not all animals utilize hemoglobin. For example, some animals, like horseshoe crabs, use hemocyanin.
