Natural indigo dye is a deep blue colorant derived from the leaves of the Indigofera plant. This dye has been used for thousands of years in various cultures around the world, particularly in India, Africa, and Japan. The dyeing process involves fermenting the leaves to extract the indigo pigment, which can then be applied to fabrics like cotton and silk. Unlike synthetic dyes, natural indigo is biodegradable and less harmful to the environment. It produces vibrant colors and has a rich history in textile arts, influencing traditional practices and modern fashion. Today, there is a growing interest in sustainable dyeing methods, including the use of natural indigo.
