Sometimes blood can look blue through our skin. Maybe you’ve heard that blood is blue in our veins because when headed back to the lungs, it lacks oxygen. But this is wrong; human blood is never blue. The bluish color of veins is only an optical illusion.
Is deoxygenated blood blue?

Why is deoxygenated hemoglobin blue?
It owes its color to hemoglobin, to which oxygen binds. Deoxygenated blood is darker due to the difference in shape of the red blood cell when oxygen binds to haemoglobin in the blood cell (oxygenated) versus does not bind to it (deoxygenated). Human blood is never blue.
Why does my blood look black?
Blood color appears darker because it has reacted with oxygen, and the majority of the water in blood will have evaporated, making a more concentrated pigmentation.

In fact, blood is made up of four components: red blood cells, white blood cells, platelets and plasma.
Why is my blood so dark and thick?
Thick blood is caused by heavy proteins, or by too much blood in the circulation. Too many red cells, white cells, and platelets will result in blood thickening. Another cause is an imbalance in the blood clotting system.
Is oxygen poor blood the same as deoxygenated?
The right side pumps deoxygenated blood (low in oxygen and high in carbon dioxide) to the lungs. The left side pumps oxygenated blood (high in oxygen and low in carbon dioxide) to the organs of the body. Deoxygenated blood enters the right atrium from the vena cava.
