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.
