Which color is the port side navigation light visible after sunset?

Explanation:
Navigation lights tell other vessels which way you’re oriented after dark. The left side (port) shows a red light, the right side (starboard) shows a green light, and the rear shows a white light. Since the port side is the left-hand side when facing forward, its light is red. A green light would indicate the starboard (right) side, and white is the stern light. So the port side navigation light visible after sunset is red.
