What do the colors of wire mean?

Blue and yellow wires are sometimes used as hot wires and as travelers, green wires (and bare copper wires) are ground wires, and white and gray wires are neutral. However, all electrical wires, regardless of their function, may carry an electrical current at some point and should be treated with equal caution.

What Colour wire goes to neutral?

Why do different colours of wiring exist? The blue wire is known as the neutral wire and its job is to take electricity away from an appliance. The brown cable – known as the live wire – actually delivers electricity to your appliance.
