What color is the port side navigation light?

Explanation:
Navigation lights are set up so other vessels can quickly tell where you are and which way you’re heading at night. The light on the port side—the left side when you’re looking forward—is red. The starboard side uses green, and a white light is shown at the stern or as an all-around light when underway. This red port light helps others judge your direction and avoid collisions, because it clearly marks your left-hand side from the front. So, the port side light is red. White lights indicate the rear, and green indicates the right side, so those colors aren’t for the port side.
