Which skin coloration is commonly associated with hypothermia?

Blue-gray coloration is the telltale sign because as the body tries to conserve heat, blood vessels near the skin constrict and blood flow to the skin drops. The blood that does reach the skin is less oxygenated, giving the skin a bluish, grayish tint—known as cyanosis—which is commonly seen in hypothermia. A bright red flush would indicate overheating or flushing from warmth or exertion, not cold. Pale white skin can occur with reduced circulation but is less specific, and a greenish tint isn’t associated with hypothermia.
