Airport marking:-

Airports also use standardized lighting and ground markings to provide direction & identification to all air and found crews. To assist pilots in differentiating at night between airport runways and freeways, airports have rotating beacon lights. These because usually flash green and white lights to indicate a civilian airport. These beacons are visible from the air long before the entire airport is recognizable. To help pilots at night quickly identify the beginning of a runway, green threshold lights line the runways’s edge. Red lights mark the ends of runways and indicate obstructions. Blue lights run alongside taxiways while runways have white or yellow lights marking their edges. All these markings & lights serve to set a safety standard for all pilots to follow.

Airport numbering:-

Runway numbers are determined by their heading, e.g. for Liverpool, runway 9/27 is facing approx.. magnetic heading 90º in one direction, and 270º in the opposite direction. If an airport has parallel runways, these would then be marked left, center and right.
