Do mid channel buoys have white lights?

Mid-channel buoys typically do not have white lights; they usually display colored lights, such as red or green, to indicate navigational information for mariners. These buoys are primarily used to mark safe passage through channels and to indicate the sides of the navigable waterway. White lights are more commonly found on buoys marking specific hazards or on navigational aids like lighthouses. Always refer to local navigational charts for precise information.
