Deoxygenated hemoglobin, which does not have oxygen, has a different light-absorbing home than oxygenated hemoglobin. This modification in absorption leads to a shift in the shade of blood from bright red to a darker shade.

The Scattering of Light
Another aspect that adds to the perception of blood vessel color is the communication between light and also the skin. When light gets in the skin, it gets spread as well as soaked up by various frameworks, consisting of capillary. This spreading phenomenon is called Rayleigh spreading.
Light with shorter wavelengths, such as blue and green, is spread even more easily than light with longer wavelengths, such as red as well as yellow. This implies that blue and also green light is more probable to be scattered by the skin, while red and yellow light can permeate much deeper.
