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.
Preferred channel markers are buoys showing red and green bands.
These are channel markers. The green buoy marks the port (left) side of the channel when entering a smaller body of water.
This depends what kinda of cans you are talking about? Are you referring to IALA-B, International Association of Lighthouse Authorities Region B Buoyage system (United States) ?Can buoys for navigation in this region are almost always green & numbered odd. There maybe yellow cans or white, which are special purpose buoys. These either mark a danger area, no wake or special instructions. Yellow buoys may have a unique special purpose.The opposite of green cans is red nun buoys, which are even numbered. Also you may find Cans or nuns marked with both red and green bands which makes them preferred channel markers.

Keep green buoys on your left when heading upstream.
Numbers are always even on red buoys in the United States. 2,4,6,8, 10 and so forth. Not sure of letters, unless they are preferred channel markers which have horizontal red and green alternating bands and are always lettered.
Red buoys have even numbers and red lights; green buoys have odd numbers and green lights.
A boat should cruise between a green and red buoy. The red buoy will always be located on the right side of your boat. Red buoys will always mean , returning, red, and right. There will be a number on a red buoy that will give the chart location. The numbers will always be even.
Sequential numbers appear sometimes on channel buoys
When heading downstream (away from harbor) leave the red buoys to port and the green buoys to starboard.When heading upstream (back in to harbor) it's the opposite: leave the green buoys to port and the red buoys to starboard.
