What color are taxiway and hold short markings?

Taxiway and hold short markings are colored yellow. This color is specifically used to enhance visibility and differentiate these markings from runway markings, which often have different purposes and can also vary in color. The use of yellow for taxiway markings helps pilots easily identify taxiways and ensures that they maintain proper orientation while maneuvering on the airport surface.

Hold short lines, which indicate where an aircraft must stop before entering a runway area, are also marked in yellow. This consistent use of yellow for these critical markings is important for safety, as it clearly instructs pilots where they should and should not proceed, particularly near runways where the traffic might be heavier.

In contrast, red is typically used for marking prohibited areas or vehicles, green is often associated with airport lighting or runways, and white is used primarily for runway markings and other types of surface markings. Understanding the color coding of various airport markings is crucial for pilots to navigate safely and effectively.
