In brief: Vasospasm
The blood vessels in your hands and feet narrow (vasospasm) causing a reduction in blood flow.
The reduced blood to this area causes the area to first turn white. With continued lack of blood to the hands and feet they turn blue. Once the spasm has resolved blood flow returns and the area turns red before returning to its normal color.
