Are nun buoys green or red?

The most common types are red nun buoys and black or green can buoys. Looking downstream, a nun will always mark the left side of the channel and a can will mark the right. They should not be passed too closely, as there’s a possibility of fouling the mooring cable or going aground if the buoy has shifted.
