External elements can influence the look of veins, such as sun tanning or making use of specific drugs, but they do not alter the fundamental shade of capillaries.

Verdict

Capillaries appear blue as a result of a combination of variables, including the dark shade of deoxygenated blood, the scattering of blue light, as well as the means our eyes regard colors. The regarded blue color of veins is an optical illusion, as all blood in our bodies is, in fact, red.
