Natural pigments are colorants derived from natural sources, such as plants, minerals, and animals. They have been used for thousands of years in art, cosmetics, and food. Common examples include chlorophyll from green plants, carotenoids from carrots and other vegetables, and ochre from clay minerals. These pigments are often preferred over synthetic alternatives because they are biodegradable and less harmful to the environment. Natural pigments can provide a wide range of colors and are used in various applications, including paint, dyes, and cosmetics, making them valuable in both traditional and modern industries.
