What colors are the sidelights on a vessel?

Explanation:
Sidelights are the navigation lights that indicate a vessel’s sides: red on the port (left) side and green on the starboard (right) side. This color pairing lets other vessels quickly judge orientation and determine safe passing, especially at night or in poor visibility. The red-on-left, green-on-right convention is standard, so red and green are the correct colors for sidelights. The other color pairings aren’t used for sidelights and correspond to different lights or special conditions on boats.
