Oh, well, yes but that's not what I meant! We call it the hemospectrum! Warm blooded trolls are more common, and have red and orange blood, then it goes all the way up to us coldblooded seadwellers, with purple and fuchsia!

Here, I drew you a picture! This is the actual color of our blood, by-the-way! I will show you sometime if you want.
