What does the color red indicate on navigational markers?

In the context of navigational markers, the color red is significant as it indicates the right side of the channel when returning from sea. This convention is part of the lateral system of buoyage used in navigation. Specifically, when a mariner is approaching from the open water towards the harbor or a safe harbor area, keeping red buoys to the right is a guide to ensure safe passage.

This color coding helps to maintain order in water navigation, allowing boaters to confidently navigate channels without confusion about which direction they should be heading. Understanding this system is crucial for safe and effective navigation, and it illustrates the importance of adhering to established maritime standards.
