You need to be more specific. The ground wire in what? If you're talking about the earth wire in electrical appliances it is yellow/green.

Ground wires are usually solid copper wires as opposed to the usually threaded conductive materials that commonly make up current handling wires. Ground should always be green or yellow. The black wire is the live wire, and white is neutral.

The ground wire is an uncoated copper wire or a wire with a green jacket if the wiring has been completed to conventional standards. In an outlet or device the grounding terminal is painted green whereas the hot terminals are normally brass and the neutral terminals are usually silver.

Most electrical systems going to a switch or a point will have two wires. One is to carry the current and the other is to ground it or bring it away. The black wire is the wire that goes to ground. Complex wiring systems may have more colors but black is always ground if wired correctly.
