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.

Mooring buoys are white with a blue horizontal band.
Red buoys have even numbers and red lights; green buoys have odd numbers and green lights.

A boat should cruise between a green and red buoy. The red buoy will always be located on the right side of your boat. Red buoys will always mean , returning, red, and right. There will be a number on a red buoy that will give the chart location. The numbers will always be even.
White with a blue band
White lights are typically found on white buoys, which are often used to mark navigational channels or indicate safe water areas. These buoys may also have additional colors or markings to provide specific information, but the primary color of the buoy is white. In some cases, white lights can also be on other colored buoys, depending on their purpose and marking system.
In coastal waters, cone-shaped even-numbered nun buoys are colored green. These buoys are used to indicate the starboard side of a channel when entering from the sea. They typically have a green color and may feature a reflective surface for visibility at night.
Some red buoys are known as "nun" buoys.(Ref: SB-4)some red buoys are known as nun buoys
Mooring buoys are white and have a blue horizontal stripe around them. Some mooring buoys are made of foam and others are made from hard, molded plastic.
