The most common colours of heat shrink tubing are black and clear (transparent), but other colours also required in some of the situations, like in the electrical power station, we usually use red, green and yellow to identify different electrodes in electrical cables, also yellow-green for the earth wire. In other industries, people also use different coloured heat shrink tubing to decorate the products they are covering, to make their products stand out from the other competitors.
