Dear Student
Any other coloured blood would either be varying proportions of the blood on earth, varying its properties. Humans are capable of naturally having blue blood. Such events have been told throughout history and about 7000 people in the world whose blood is blue. This occurs with the mother eating a lot of copper filled foods during the incubation of the embryo and its development into a fetus. From what I know about this matter their flesh is still the same, just all the veins running in it, all the capillaries running through it carry blue blood giving it a bluish colour. The same would apply for the other known blood colours and thief tones/proportions.
