What Is Gray Skin?

Pallor or grayish or blue skin is a result of a lack of oxygenated blood. Your blood carries oxygen around the body, and when this is disrupted, you see a discoloration. The disruption may be to the flow of blood itself, which produces paleness and/or a gray tint to skin tone. When you experience a lack of oxygen, your blood may still be flowing, but it changes color. This causes your skin to become blue or gray in color.
