The threshold and departure ends of the runway are marked by what color lines, respectively?

The color cues used here are about quickly signaling which end of the runway is intended for landing versus departing. Green lines mark the threshold end—the start of the usable landing area—so pilots see a clear green boundary as they approach. Red lines mark the departure end, serving as a visual boundary for the far end and indicating that landing beyond that point is not intended. This green-for-threshold and red-for-end convention provides an immediate, standardized cue to pilots, which is why this pairing is considered the correct one. Other color combinations don’t align with this standard signaling approach.
