The stern light on a vessel is typically white with a 135 degree cone of visibility. From the 1980 US Inland Rules only pilot vessels, vessels aground, vessels not under command or vessels with restricted maneuverability may show red astern. The combination and orientAtion of red and white all-around lights is dictated by category. A towing vessel shall have a yellow light above it's stern light whether towing behind or alongside. The 1972 International Rules do not provide for the yellow towing light astern when the towed vessel is alongside of the towing vessel. Lastly, a sailing vessel under 20 meters in length may at her option display an all-around red over green at her masthead. As a matter of common practice the author has never actually seen this.
The 'a' is Old English for 'onward' - so ahead is onwards forward and astern is onwards backwards.
