The Oxygen Hits The Chemicals In The Blood Turning It Red Instantly, But Even Though Your Body Has Oxygen In It And Through The Blood It Needs A Certain Amount To Do That.
Hemoglobin makes the red color.

Haemoglobin
Red blood cells (RBCs) contain a protein called hemoglobin, which binds to oxygen and gives them their red color. When RBCs are oxygenated, they appear brighter red, and when deoxygenated, they appear darker red. This is why blood in arteries, where oxygen is bound to hemoglobin, appears brighter red compared to blood in veins.
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.
Blood is red because of the iron in red blood cells, which gives it a red color when oxygenated. Veins appear blue because of the way light interacts with the skin and the blood vessels, causing them to look blue from the outside.
Veins appear blue because of the way light interacts with the skin, making them look that color. Blood is actually red because of the iron in red blood cells, which gives it its hue.
Blood cells that are carrying oxygen will appear bright red, while blood cells that are not carrying oxygen will appear darker in color (usually dark red or purplish). This change in color is due to the presence or absence of oxygen-binding molecules like hemoglobin within the red blood cells.
Red blood cells (erythrocytes), are red in color because they contain hemoglobin. The heme component of hemoglobin contains iron, thus giving it a red color.
red, to remember this all you have to do is think of death that makes you think of blood and blood is red.
Oxygen is the gas transported by red blood cells that gives them a bright red color.
then they are red if they are not carrying oxygen then they are a purple red.
