The most common line marking colours used in warehouses are yellow, white, red, and blue. Yellow is typically employed for pedestrian walkways and safety zones, ensuring clear visibility and reduced risk of accidents. White is often utilised for general warehouse floor lines and operational areas. Red is reserved for hazardous zones and restricted access areas, while blue indicates equipment and machinery placement.
