What light color is typically associated with a North Cardinal Mark?

A North Cardinal Mark is designated to indicate that safe water lies to the north of the mark itself. The light color that is typically associated with a North Cardinal Mark is white. This choice aligns with the IALA Maritime Buoyage System, where white lights are used to convey the message of navigation and safe passage areas.

In the IALA system, each cardinal mark has specific color and light characteristics to guide vessels safely through navigational challenges. The North Cardinal Mark's white light, which is often complemented by a pattern of light (such as flashes or a continuous light), helps mariners identify it from a distance and understand the navigation signals provided. This uniformity in color and signaling allows for clear communication and enhances safety for vessels traveling in maritime environments.
