Hemoglobin is the protein in red blood cells that carries oxygen, giving blood its red color.
Blood will appear bright red when it has high oxygen content. This is because oxygen binds to hemoglobin in red blood cells, forming oxyhemoglobin, which gives the blood its bright red color.
the answer is that i dont know
No, blood is never blue. Blood appears blue in veins due to how light is absorbed and reflected, not because of its color. Once it comes in contact with oxygen, it appears red because of the presence of hemoglobin.

Blood is always red.
Blood is bright red due to the high concentrations of oxygen in it. This blood is known as oxygenated blood. Blood that appears dark in color or "blue" is blood that has been used by the body and has a higher concentration of carbon dioxide in it. This blood in known as deoxygenated blood!
When blood lacks oxygen, it appears dark red or maroon in color.
Human blood has red color when oxygenated which is mainly because of red blood cells. Its color changes to purple when present in oxygen deprived circumstances. To restore the color the blood has to be placed in oxygen rich environment.
Spiders have blue blood. In human blood oxygen is bound to hemoglobin which contains iron, giving it the blood a red color. In spiders, as well as other Arthropods and Molluscs, oxygen is bound to hemocyanin which contains copper, giving its blood a blue color. The same interaction that causes oxygenated blood to color, also causes iron rust to appear reddish and the oxidized copper to appear green. However, I have noticed no color in spider blood before.
Oxygen-poor blood is dark red; oxygen-rich blood is bright red.
Hemoglobin is the protein in red blood cells that carries oxygen, giving blood its red color.
Capillaries change color as they pass by body cells as the blood they contain loses oxygen. Oxygen-rich blood has a brighter color than oxygen-poor blood.
When blood cells have oxygen they are red, when they have no oxygen they are a darker shade of red.
red
Purple or blue The blood becomes red when it gets contact with oxygen this is why when you get blood drawn it looks purple or blue
