Oookay so well today I remembered that certain sea creatures have blue blood instead of red, and after doing a little research on the subject, I realized that the entire troll hemospectrum could possibly be feasibly explained with different amounts of the different proteins hemoglobin, hemocyanin and hemerythrin! Sorry if it’s a little too sciency for one’s tastes but do let me know if I’ve gotten anything wrong!
(If it’s something like ‘individual organisms can’t produce more than one oxygen-binding protein at once’ well my friend please do remember that the subject matter is a species from a different universe that breeds in a similar manner to ants, bees and termites, and we can probably find a way to work around it anyhows)
I knew it was a chemical! I’ve been searching my textbooks for an answer, and now it makes more sense then ever.
