Light from veins must penetrate through layers of skin and fat before it reaches the eyes of the observer. Since red and blue colors are of two different wavelengths, they penetrate the skin with different degrees of success. As a result of this, bluish-green light is reflected off the blood and reaches the observerβs eyes, making our veins appear blue.
