What color are taxiway and aircraft stand markings?

Taxiway and aircraft stand markings are predominantly colored yellow. This color is chosen for its high visibility, allowing pilots and ground personnel to easily identify and distinguish these vital markings from other elements on the airport surface. Yellow markings help to define taxi routes, show where aircraft should hold short of runways, and indicate parking positions or zones, contributing to safe and efficient ground operations.

While other colors are used for different purposes at an airport—such as white for runway markings and red for prohibited areas—yellow is specifically designated to ensure clarity and safety in aircraft movement on taxiways and at stands. Understanding the colors of markings is crucial for pilots, especially when navigating the often busy and complex environment of an airport.
