Citadel Base: Zandri Dust is a high-quality acrylic miniature paint, it is engineered with a rich, heavy pigment load to deliver an opaque foundation layer over black or white undercoats with a single stroke, color family: a deep, warm, khaki earth and desert tone.
It skews slightly darker, greener, and more muted than Morghast Bone. It is a classic foundational sand hue used universally for military uniforms, leather, arid terrain, and heavily weathered structures.
Non-toxic, water-based acrylic, best used for: basecoating desert camouflage, Cadian Shock Troops uniforms, parched leather, aged scrollwork, and arid terrain pieces. 
It acts as a perfect baseline for shading with Agrax Earthshade or layering up with Ushabti Bone.
