What color wires are used for TV?
Just because a wire is a particular colour, that doesn’t always mean that the colour code applies. For example, many TV aerial cables are coloured brown, which indicates a live wire under the wiring colour codes. However, TV aerials do not carry any voltage and aren’t subject to the same safety considerations as live wires carrying electricity to appliances are. Similarly, you will find plenty of black cables around the average home. Many of these carry electricity from your mains supply to your appliances, but they have the same colour as the neutral wires.
Why are wires color coded?

What color is the neutral wire?
You must ensure that there is no power source connected with the live wire before working on the wiring. The neutral wire colour is blue.
What is the difference between blue and brown wires?
The blue wire, also referred to as the neutral wire, has the function of transferring electricity away from the appliance. The brown wire, otherwise known as the live wire, transfers electricity to the appliance. The combination of these wires is referred to as a circuit. You should be aware that some properties have old-style wiring, which should be regularly checked by an electrician to ensure that it remains in good working order. The need for replacement will be entirely dependent on the safety of the wiring.
How many wires are in a three phase system?

Step 1
Unscrew the three screws on the back of the plug. They should be loose enough to allow a wire to be inserted into the contact points without the screw falling out completely.
Step 2
Strip 2 inches of plastic sheath from the wire. There should be three smaller wires within the sheath. Strip a half-inch of sheath from each of the smaller wires. Twist the exposed copper section of each of the three wires into a tight bunch.
Step 3
Insert the wires into the corresponding contact points. The colors of your wire may vary depending on whether you are using standard flex or building wire. Insert the active wire (brown or red) into the contact point marked "A". Hold the wire in place and tighten the screw to secure the wire.
Step 4
Unscrew one screw from the main cable holder and remove the screw completely. Most plugs use a small plastic "gate" secured by screws to hold the cable in place. "Swing" the gate open and place the wire in the holder. Close the gate again and secure the screw back into place. Make sure the wire is held in place around the outer sheath.
