ML6604 presents a soft, understated surface characterized by gentle tonal variations and a subtly organic feel. The material appears to be a light, warm gray or off-white stone, perhaps resembling fine limestone or a lightly weathered ceramic tile. Across the surface, faint shifts in shading give the texture depth. These variations are not bold or highly contrasting; instead, they form a quiet interplay of slightly darker and lighter patches that blend seamlessly into one another. Very fine, almost imperceptible lines run diagonally in places, resembling gentle veining or the subtle marks left by natural sediment layering.
