What color is a nun buoy typically painted?

A nun buoy is typically painted green. This is an important aspect of navigational aids in maritime operations. Nun buoys indicate the starboard side of a channel when returning from sea, and they are part of the IALA buoyage system, which is used internationally. In this system, red buoys, which correspond to the color typically associated with nun buoys in some regions, denote the port side when returning to port from the sea, contrasting with green markers that indicate the starboard side. Thus, the color of a nun buoy is specifically green, serving as critical information for navigational safety. Understanding these color codes is essential for mariners to ensure safe transit through channels and harbors.
