Isolated danger buoys are moored in navigable waters to indicate the presence of an underwater hazard, such as rocks or wrecks, that is not immediately visible. These buoys typically have a black and red color scheme, with two black spheres on top, and are positioned away from the danger they mark. They are used to guide vessels safely around the hazard, ensuring safe passage through the area.
Yellow represents caution on these buoys. Usually meaning to stay away from them. They are used to indicate pipes, dredge lines, traffic schemes, an isolated danger.

No, red buoys are not known as can buoys. Red buoys are typically referred to as "nun buoys," which are conical in shape, while "can buoys" are green and cylindrical. These terms are part of the U.S. Aids to Navigation System, which uses color and shape to indicate safe passage in waterways.
Can buoys are typically orange in color. This bright hue is designed for visibility and safety, making them easily identifiable in various water conditions. In some cases, specific markings or reflective materials may also be used to enhance visibility further.
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.
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.
