On a Preferred Channel Mark, what do the top and bottom colors indicate?

The colors on a Preferred Channel Mark tell you how to pass the mark in relation to the channel. The top and bottom colors indicate the direction of the preferred route through the channel—essentially which side of the buoy you should pass on to stay in the designated channel. They do not convey depth, speed to pass, or the manufacturer.
