No particular ship. When you get the torpedo warnings they will say "Red" or "Green". I learned in my 22 year naval career that "Left" and "Port" have four letters. That leaves "Starboard' meaning "Right".
Port and Starboard never change on a vessel since the bow is the reference point. Facing aft can be a bit confusing but there has to be some challenges in a Sailor's live.
If you check a British Sailor's hat the left side of the inside top is red and the right side is green. If the poor Bloke is p----- (drunk) he can always tell how his hat is to be worn.
