Tibetan Monks Make Sand Mandala, Placerville, California, United States

The colors for the painting are usually made with naturally colored sand, crushed gypsum (white), yellow ochre, red sandstone, charcoal, and a mixture of charcoal and gypsum (blue). Mixing red and black can make brown, red and white make pink. Other coloring agents include corn meal, flower pollen, or powdered roots and bark.
Ritual destruction
The destruction of a sand mandala is also highly ceremonial. Even the deity syllables are removed in a specific order, along with the rest of the geometry until at last the mandala has been dismantled. The sand is collected in a jar which is then wrapped in silk and transported to a river (or any place with moving water), where it is released back into nature. For this reason, the materials keeping with the symbolism are never used twice.
