What color is the blood in your body?

Your blood is actually always red! Blood in your veins has very little oxygen and is a dark red color that looks almost blue when covered by your skin. Your arteries have bright red blood because it has a lot of oxygen in it that is being carried throughout your body to be used by tissues.

Hereof, is your blood always red?

If Blood Is Red, Why Are Veins Blue? Blood is always red, actually. Veins look blue because light has to penetrate the skin to illuminate them, blue and red light (being of different wavelengths) penetrate with different degrees of success. What makes it back to your eye is the blue light.

Can blood be a different color?

Animals may transport some materials in a different way from humans, however. In humans, oxygenated blood is bright red and deoxygenated blood is dark red or maroon. The color is due to the presence of hemoglobin molecules in the red blood cells. Blood that is not red indicates a health problem.
