What colors are spherical buoys that mark fairways and navigable channels?

Spherical buoys that mark fairways and navigable channels are typically colored red and white striped. This color scheme is part of the United States Aids to Navigation System, where red indicates the right side of the channel when approaching from the open sea or heading toward a harbor. The white stripes help distinguish these buoys from other types and convey information about their specific purpose in navigation.

This combination serves both a functional and a visual purpose, as it enhances visibility against various backgrounds and weather conditions, allowing boaters to easily identify safe passage routes. Understanding these color codes is crucial for safe navigation and compliance with maritime regulations.
