The wall is composed of horizontally stacked blocks of varying sizes, exhibiting a range of translucent hues from pale off-white and light orange to deeper amber and reddish-brown. Light sources positioned behind or within the wall cause the salt bricks to glow with differing intensities, highlighting their crystalline structures and natural striations. Brighter, more luminous sections contrast with darker areas, indicating variations in material density or light diffusion. No individuals, external objects, or specific actions are depicted within the scene.
