Why is blood red?

Blood is red because of the presence of a pigment called hemoglobin. Hemoglobin is a protein found in red blood cells that carries oxygen throughout the body. When oxygen binds to hemoglobin, it gives blood a bright red color. However, when oxygen is released from hemoglobin, blood appears darker red or even maroon. The color of blood can also be influenced by other factors such as the amount of oxygen present, the concentration of hemoglobin, and the presence of other chemicals or substances in the blood.
