If your fingernails are blue/purple, you're not getting enough oxygen. If you're often cold, your oxygen circulation is limited, so your fingernails will turn blue. http://funadvice.com/r/14oi9129ljk includes treatments for your fingernails.
this could be the result of not enough blood flow to the fingertips, or exposure to cold for too long (frostbite). also, if you crush your fingers in something, or get them stepped on or hit etc, they could be bruises.
