What color is a buoy that indicates an isolated danger?

A buoy that indicates an isolated danger is colored black with one or more horizontal red bands. This specific color scheme is easily recognizable, ensuring that mariners can clearly identify navigational hazards in the water, such as submerged rocks or wrecks that present risks to navigation.

The reason for this color combination is to provide a clear visual cue that distinguishes isolated danger buoys from other types of navigational aids. The black color symbolizes danger, while the red bands signify caution and alert mariners to navigate around the area. Isolated danger buoys are typically positioned away from safe passages, guiding boaters to the appropriate routes while indicating where not to travel.

Other buoy colors serve different purposes; for instance, red buoys usually indicate the right side of a channel when returning from the sea, while green buoys mark the left side. Understanding these color codes is essential for safe navigation and helps prevent accidents at sea.
