Raynaud's disease can cause this. It is a temporary vasoconstriction of the small arteries in the fingers and toes triggered by cold.

Vasoconstriction of the vessels can cause nails to turn blue. Known as raynaud's phenomenon, the constriction causes a loss of bloodflow in the area and improper oxygenation. The bluish color is described sometimes cyanotic. Another cause of blue nails can be from trauma due to a subungual hematoma (blood blister under the nail).
