What is the colour of hemoglobin and oxy hemoglobin?

Well, the high concentration of hemoglobin is what gives our
blood its red color. More specifically, the porphyrin
functional group in the hemoglobin structure is what gives
hemoglobin (and oxy-hemoglobin) its red hue.
DO NOT LET ANYONE TELL YOU THAT HEMOGLOBIN IS RED BECAUSE OF THE
IRON IN THE CENTER OF ITS STRUCTURE. THEY WOULD BE LYING TO
YOU.
