What color are runway markings?

Runway markings are typically white to ensure high visibility against the runway surface, which is often grey asphalt or concrete. This color choice is consistent across many international regulations and helps pilots easily identify runways, especially in low visibility conditions. The use of white for runway markings is standardized in aviation to promote safety and consistency in identifying key runway information, such as the runway number, centerline, and threshold markings.

Other colors, such as yellow, are used for taxiway markings and general surface signs, while red and blue serve different purposes in airport lighting and marking systems, which are not directly related to runway identification. Understanding the significance of these colors in the context of aviation helps pilots navigate airports safely and effectively.
