It is actually the name given to the molecule found in the RBCs that is carrying oxygen. It is called oxyhemoglobin.
Hemoglobin.
The term for a low amount of oxygen in blood is called cyanosis. It refers to the bluish color of some body tissues, like the lips, because cyan is the name of a shade of the color blue. Or it can be called anemia if it is due to the low number of healthy red blood cells that carry oxygen.
The protein "Hemoglobin" is responsible for the red color. Each hemoglobin molecule can bind up to 4 oxygen atoms. When fully loaded with oxygen atoms the protein takes on a more bright red color. When deprived of oxygen the protein takes on a darker red/blue color.

The name of the blood vessel which supplies glucose and oxygen to the heart muscle is an artery. Arteries carry blood away from the heart.
The red blood cells carry oxygen to the tissues, absorb CO2, then carry it away to the lungs to get rid of it. Haemoglobin is the name of this magic chemical. Some animals use a copper-based equivalent which is blue!
Blood.
Proteins don't give blood its color, the great amount of red blood cells do. Hence the name, they are red and give blood its color.
The substance that help the blood carry oxygen is called hemoglobin.
