I am trying to replace a very old light fixture that was attached to a medicine cabinet in my bathroom. I should also add that it was fluorescent. The problem I'm having is that the old fixture only has a white and red wire. The new fixture has white black and green wires. Is it possible to use the new fixture?

What are colors of wires coming out of wall? If wires coming out of wall, black to black-white to white- green (ground) to metal box.
