The gray pattern is naturally distributed on the white background. The shades of gray vary from light gray to dark gray, forming a sharp contrast with the white, making the whole pattern more layered and three-dimensional. It is often used for interior and exterior wall decoration of buildings, such as the walls of halls, corridors, elevators, etc. in hotels, shopping malls, office buildings, and residences, which can create an elegant and atmospheric atmosphere; it can also be used for floor paving, such as the floor of living rooms, bedrooms, and restaurants, adding a sense of luxury and elegance to the space.
