Capillaries are commonly blue or purple in shade when seen from the outside because of the way light is soaked up and shown by the skin and blood vessels. The skin and subcutaneous tissue have a layer of fat that absorbs the majority of the shades in the noticeable light range, except for blue and violet wavelengths, which are spread and shown back to our eyes.
When light passes through the skin and gets to the blood vessels, the red blood cells in the veins take in most of the red light and show heaven light back to the viewer. This phenomenon, referred to as Rayleigh scattering, causes the blood vessels to appear blue to the naked eye.

Variables Affecting the Appearance of Blood vessels
