• Vein Deepness: Veins closer to the surface of the skin appear blue due to the means light engages with the skin.
• Light Spectrum: Shorter wavelengths of light, like blue and green, pass through much deeper right into the skin, causing blood vessels to look blue.
• Subcutaneous Fat: The amount of fat under the skin can affect the exposure of capillaries.

Physical Aspects

Final thought

While the common idea that blood vessels are blue because of the shade of the blood is a misconception, there are numerous reasons capillaries appear blue with the skin.
