In the context of plumbing and piping systems, the color code for pipes is standardized to ensure clarity and safety in identifying the type of fluid carried by the pipes. For pipes that are carrying saltwater, the designated color is usually green. This coding helps workers and maintenance personnel quickly recognize the purpose of the pipes and avoid confusion with other types of fluids, thus enhancing safety when working in environments where various systems intersect.

This coloration serves a critical function in preventing errors, such as connecting to the wrong pipe or mishandling during repairs. Understanding these color codes is essential for anyone involved in the construction, maintenance, or inspection of buildings to adhere to safety regulations and ensure the proper functioning of systems.
