The difference between blue and red veins primarily relates to the oxygen content of the blood they carry. Red veins, or arteries, carry oxygen-rich blood from the heart to the body, giving them a bright red color. In contrast, blue veins are typically veins that carry oxygen-depleted blood back to the heart, which appears darker and can look blue through the skin due to the way light penetrates and reflects off the skin. However, the blood itself is never truly blue; the blue appearance is an optical illusion.
