What color lights are used in airport lighting to outline taxiways?

Taxiways at airports are outlined with blue lighting. This specific color is standardized and provides clear visibility for pilots to navigate the taxiways safely, especially during nighttime or low-visibility conditions. Blue lights help distinguish the taxiway from the runway and other areas of the airport, minimizing confusion and enhancing safety. The use of blue lights is part of a broader system of airport lighting designed to assist pilots in ground operations. By contrast, other colors such as red, yellow, or green serve different purposes; for example, red lights indicate stop bars, yellow lights are often used to provide warning or caution, and green is typically used to signify runway approach lighting. Understanding the significance of each color helps in recognizing their role in airport operations.
