Natural colors refer to hues derived from natural sources, such as plants, minerals, and insects. These colors are often used in art, textiles, and food, providing a more organic and eco-friendly alternative to synthetic dyes. Examples include indigo from the indigo plant and cochineal from the cochineal insect. The use of natural colors has a long history, dating back to ancient civilizations that relied on their surroundings for pigments. Today, there is a growing interest in sustainable practices, leading to a resurgence in the use of natural colors in various industries, promoting environmental awareness and health benefits.
