The skin of caucasians does not contain much melanin, and is slightly transparent. The capillaries in the skin are what give us our slightly pink color, as long as the blood contains a healthy dissolved oxygen content (red blood). Blood that has had oxygen exchanged for carbon dioxide looks more blue. If the CO2 cannot be exchanged efficiently in the lungs it returns to the capillaries more blue than usual, so parts of our bodies look blue (especially the lips and fingernails). Also, if the core temperature is lowered, the body can reduce the blood flow to the extremeties so the exchanged corpuscles don't get to return to the lungs fast enough.
