What color is the stern light on a vessel underway at night?

When a vessel is underway at night, it must show navigation lights to convey its orientation and status. The light at the stern is white, placed at the back so others behind can tell the vessel is moving away from them. The red and green lights mark the port and starboard sides, respectively, helping nearby mariners determine the vessel’s direction. Blue isn’t used for standard navigation lights. So the stern light is white.
