What color marks the threshold line on runways?

Runway markings use standardized colors to convey different surfaces, and the threshold line is painted in white. This white color ensures high visibility and consistency with other runway markings like the threshold itself, aiming point, and numbers, making it easy for pilots to identify where landing should begin. Yellow is used for taxiway markings, blue for taxiway lights, and green isn’t used for runway threshold markings, so the color that marks the start of the landing area is white.
