We know that the shape of the heme group and the hemoglobin protein changes, depending on whether hemoglobin is oxygenated or deoxygenated. Therefore, these two conformations must have different light-absorbing properties. Recall that the color of a substance is the complementary color of what it absorbs. The oxygenated conformation of hemoglobin absorbs light in the blue-green range, and it reflects red light. This property accounts for the red appearance of oxygenated blood. On the other hand, the deoxygenated conformation of hemoglobin absorbs light in the orange range, and it reflects blue light.
