Final answer:

The color of the trailer service line and emergency air lines is blue.

Step-by-step explanation:

The color of the trailer service line and emergency air lines is blue.

In an air brake system, the trailer service line carries air pressure from the tractor to the trailer for application of the trailer brakes.

The emergency air line, on the other hand, supplies air to the trailer brakes in case of an emergency, such as separation from the tractor.
