Logwood dye is a natural dye derived from the heartwood of the logwood tree, primarily found in tropical regions like Central America. It has been used for centuries to produce rich shades of black, blue, and purple in textiles and other materials. The dye is extracted by boiling the wood, which releases its color compounds. Historically, logwood dye played a significant role in the textile industry, especially during the 18th and 19th centuries. It was highly valued for its ability to produce vibrant colors and was often used in the dyeing of cotton, wool, and silk. Today, it is still used in some artisanal dyeing practices.
