Indigo is a deep blue color that comes from the indigo plant, which has been used for centuries to dye fabrics. This rich hue is often associated with calmness and creativity, making it a popular choice in art and design. The dye extracted from the plant was historically significant, especially in regions like India and West Africa, where it played a vital role in trade. In addition to its aesthetic appeal, indigo has cultural importance. It is often linked to traditional crafts, such as batik and tie-dye, where artisans use the dye to create beautiful patterns on textiles. Today, indigo is still widely used in fashion, especially in denim jeans, giving them that classic blue look.
