In brief: Black Skin

Extreme cold is directly toxic to the skin cells and the blood nourishing the cells.
The skin dies and dead skin is black.

In brief: Lack of blood

The skin turns black because there is a lack of blood flow to the area with frostbite.
Frostbite causes blood vessels to vasoconstrict (close). With no blood flow to the affected area, the skin becomes necrotic, which causes the skin to turn black.
