Indian Rustic slate has a bright yellow foundation with rust marks on the surface generated by surface oxidation. Indian Rustic is great for giving your house or business a light rustic appeal. Because Indian Rustic slate is one of the most vivid and brilliant slates, any installation of Indian Rustic slate will have a warm and vibrant feel to it.
