Indigo dyeing is a traditional method of coloring fabrics using the natural dye derived from the leaves of the indigo plant. This process involves fermenting the leaves to create a blue dye, which can then be applied to textiles. The dyeing technique often requires multiple dips in the dye bath to achieve the desired shade of blue. The process of indigo dyeing is unique because the fabric appears green when first removed from the dye bath, turning blue as it oxidizes in the air. This ancient practice has been used in various cultures around the world, making it a significant part of textile history.
