indigo pigment

Indigo pigment is a natural or synthetic dye known for its deep blue color. Historically derived from the indigo plant, it’s processed to produce a vibrant, lasting blue used in textiles, especially denim jeans. The dye works by attaching itself to fibers in fabrics, resulting in a rich coloration that doesn't fade easily. Indigo's chemical structure contains nitrogen and carbon, which give it strong colorant properties. Its develop­ment revolutionized clothing dyeing, making blue fabrics widely accessible and durable, and it remains one of the most iconic and enduring pigments in fashion and art.
