Earth pigments are naturally occurring minerals used as colorants in various forms of art, especially in painting and printmaking. These pigments are derived from the earth's crust and often include oxides and clays, which provide a wide range of colors, including browns, reds, yellows, and greens. They are valued for their stability, lightfastness, and non-toxicity, making them suitable for experimental printmaking techniques that emphasize organic and sustainable practices.
