Because you are cutting off the blood flow to the tip of your fingers

When we put rubberbands around our fingers our flow of blood stops and due to lack of blood the fingertips become cold and white

Yes. Your circulation is what keeps you warm and gives you your pinkish color. Once you stop the blood flow to that part of your body it becomes cold and white

And let me know if I am wrong, but that's not good to do. If you leave it like that for a while it can do some damage
