"Red to red and white to white" is a common phrase used in the context of boating and navigation, referring to the color of navigation lights on boats. The rule of "red to red and white to white" means that you are in a safe position if you see the other vessel's red light on your right (starboard) and its green light on your left (port), indicating that the vessel is moving from your right to left. If you see both the red and green light in front of you, the vessel is heading directly towards you, and it is not safe. Similarly, "white to white" means seeing both the stern (rear) and masthead (front) white lights of a vessel, indicating it is moving away from you. In the context of the game, the magflow link has red light when incomplete and white when completed.
