What color are the paint markings that outline vehicle service roads and passenger walkways?

The paint markings that outline vehicle service roads and passenger walkways are white. This color is used for these markings to provide clear visibility and contrast against the surrounding surfaces, ensuring that both vehicle operators and pedestrians can easily identify the designated areas. Utilizing white paint is a standard practice in many airports and is part of a broader safety strategy to avoid accidents and ensure efficient navigation in airside environments. Clear and universally recognizable color-coded markings are crucial in maintaining order and safety in high-traffic areas, and white serves this purpose effectively.
