After the blood leaves the human body for a period of time, the color will become darker and darker during the coagulation process. Menstrual blood is due to the shedding of female endometrium, which is mixed with 75% arterial blood and 25% venous blood, and its quantity and speed also determine the color.

Although fresh menstrual blood is bright red, it is kept in sanitary napkins for a period of time after bleeding from the body, which gradually reduces the oxygen content of hemoglobin in the blood.
