feet turn blue when they are really cold and when there is barely any oxygen getting to them
If you are very cold, you are not breathing properly, or your circulation is restricted, your oxygen levels may drop. When your blood is less oxygenated, the color of the blood becomes darker. When it is viewed in areas that the veins and capillaries are close to the surface, it will appear blue. This is especially noticeable in the fingers, toes, and lips.
It just means that you ate or drank something that caused it to turn blue, for example: A blue ice.
Sounds rather like poor circulation. Lack of oxygen in the feet (or elsewhere) could cause cyanosis, and that makes the skin look blue. When the blood supply has been cut off from, say, the feet, and then returns, tingling is sometimes felt.
