What the color of buoys mean?

Buoys are color-coded to convey specific information to mariners. Red buoys typically indicate the right side of a channel when returning from sea (often referred to as "red right returning"), while green buoys mark the left side. Other colors, such as yellow or white, may indicate specific navigational hazards or special areas. Additionally, the shapes and markings on buoys can provide further information about their purpose and the surrounding waters.
