Preferred channel markers are buoys showing red and green bands.
The main purpose of the lateral system of red and green buoys and markers is to indicate the sides of a navigable waterway or the location of hazards. Red buoys/markers should be kept on the right or starboard side of the boat when traveling upstream, while green buoys/markers should be kept on the left or port side. This system helps to ensure safe navigation and prevent collisions.
To mark the shipping channel.
Keep the marker to your port (left) side. Heading down stream it'll be to starboard. Usually there will be a red marker to the starboard headed upstream, and you should keep between the buoys , sometimes there will be midstream buoys, or even preferred channel markers, marking safe deep water channels. They will be red over green, triangular, lettered or even numbered for starboard markers, and green over red, square, lettered or odd numbered for port side markers. Center channel markers may be yellow or white, hazard markers are black over white, or black over red. Inter-coastal waterway markers are yellow. States have their own marker systems, heading up current though in all systems will be green to port, red to starboard and black marking hazards. Lighted markers follow the same rules, green to port, red to starboard and white for hazards heading in from the sea/ocean. If the lights are moving they're on a vessel, stopped or anchored vessel should only show a white light or lights. Yellow lights indicate a vessel under tow.
"Dry Erase markers come in a very wide range of colors. While the markers originally only came in black, red, blue, and green; they are now available in rainbow colors and even neon."

These are called preferred channel markers. Which means you can pass on either side, however whatever color the topmost color is is the preferred passing side. Topmost Green prefer to pass on Starboard (right) Topmost Red prefer to past on Port (left). There are sometimes lit, sometimes lettered, never numbered.
