In night operations, what color is the starboard sidelight on a power-driven vessel underway?

The starboard sidelight is green. Navigation lights are standardized so you can quickly tell a vessel’s direction: red on the port side, green on the starboard side, with white lights for the stern and, on larger vessels, a white forward light. On a power-driven vessel underway, the starboard sidelight must be green, helping others determine bearing and passing rights at night. Red would indicate the opposite side, white is used for the stern/masthead rather than the sidelight, and blue is not used for standard navigation lights.
