      Blue blood = deoxygenated or oxygen deficient blood.
      Red blood = oxygenated or oxygen rich blood.

      More blue blood means less oxygen supply to the body.

      except that the deoxygenated blood is not blue, but dark red

      Well, yeah but with "blue" blood valencialiew meant deoxygenated blood. That’s the convention.

      blue blood is not literally blue in color…
