Hello! I'm sorry if this is the wrong place to ask, but everywhere else I looked would only give me resources on real life blood disorders, while I'm asking for a definitive answer to a hypothetical question that seems like only a haemotologist can answer.

If there was a person who had green blood for the same reason skinks of the Prasinohaema genus do (elevated levels of biliverdin), and their face flushed because they were embarrassed or from physical exertion, would it be green or red? Basically, how much of a blush is determined by plasma being the 'normal' amber colour vs blood cells being red? Would an excess of biliverdin override the redness of a blush, or would it simply tinge the skin until a flood of highly-oxygenated erythrocytes pulls it back to red again? Note that this blood is still ferrous and uses iron, not copper. Skink rules, not vulcan rules.
