This classic book, previously published by British Museum Press, is now an Archetype title. Indigo tells the compelling and comprehensive story of the world's oldest, most magical, and best-loved dye. Produced from plants by a process akin to alchemy, indigo has a unique chemistry that renders it compatible with all natural fibre. From the time of the ancient Pharaohs it made an incredible impact worldwide as the world's only source of blue of every hue, being the mark both of 'blue-collar workers' and of aristocrats wearing 'royal blue'. It was also indispensable for creating a glorious range of colours in combination with other natural dyes, it provided paint and medicine, and it featured in many rituals. Its fascinating history continued after the invention of synthetic indigo, used to dye the world's most popular garment, denim jeans. For environmental reasons, indigo from nature is making a comeback today in many countries.
