What does it mean when your nail beds on all your fingers turn dark purple?

This is called cyanosis. It indicates that there is a decrease of oxygenated blood to the area. This occurs when it is cold and the blood supply to the extremities is decreased so that blood can go to the vital organs. Run your hands under warm water or rub them together and you will see your fingers turn back to their normal color.
