What does the color yellow denote on a buoy?

The color yellow on a buoy signifies caution and alerts boaters to potential hazards in the vicinity. This could mean areas that are unsafe due to shallow waters, obstacles, or other dangers that require increased vigilance. Yellow buoys often advise boaters to proceed with care, making it important for navigators to pay close attention to their surroundings when approaching these markers.

In contrast, other buoy colors have specific meanings that do not relate to caution. For instance, certain colors signal safe passage or indicate controlled areas, while the implications of a channel marker or a restricted area are shown through different color schemes. Understanding these color codes is crucial for safe and effective navigation on the water.
