In brief: Red, White, and Blue
Named after a french physician, raynaud's is improper regulation of blood flow.
Pain and changes to the colors of the fingers and hand in response to cold (air conditioning, ice cubes, etc) or stress occurs as follows: the fingers turn white as the blood vessels constrict, then turn blue as the oxygen levels drop, then turn red upon rewarming. Usually benign, but see your doctor to be sure!

In brief: Vasoapastic response
Raynaud's phenomenon is an exaggerated vasoapastic response to cold weather and stress.
The blood vessels of the extremity normally dilate and constrict with temperature changes. This occurs to an extreme degree in patients with raynauds. They will experience blue or white fingers or toes when exposed to cold temperature or stress. This is self-limiting and rarely causes significant problems.
