If blood is red why do your veins look blue? SDStaff Hawk replies: Blood is a bright red in its oxygenated form (i.e., leaving the lungs), when hemoglobin is bound to oxygen to form oxyhemoglobin. It's a dark red in its deoxygenated form (i.e., returning to the lungs), when hemoglobin is bound to carbon dioxide to form carboxyhemoglobin. Veins appear blue because light, penetrating the skin, is absorbed and reflected back to the eye. Since only the higher energy wavelengths can do this (lower energy wavelengths just don't have the *oomph*), only higher energy wavelengths are seen.

Is the color of your blood inside you blue? Rating Newest Oldest. Best Answer: Blood is bright red when it contains oxygen, and it is a dark reddish-maroon when it doesn't contain oxygen. It is never blue, even when it is inside the body. The blue color is simply the veins themselves with dark blood within. They show up as blue because they are under the skin, and blue is the only (visible) wavelength with enough energy to penetrate that deep and reflect back out.
