The blood in the veins is red, but appears to be blue, especially in older people, when seen through the skin.
Veins appear blue or purple due to the way light interacts with the skin. It's not their actual color. Veins look blue when seen through the skin as only low-frequency light, such as blue or violet, can penetrate deep enough to illuminate them.
