*Introduction of Lecture:
by Yoshiko Iwamoto Wada
Following the use of mineral based pigments as colorants for body, cave walls and fiber, indigo was one of the earliest dyes to color textiles. Ms Wada will look at indigo textiles and the color blue in its social context including class, religion, decorative processes, and fashion. Indigo plants are one of the most prevalent sources of dye in the world. There are over 10 plant species that contain significant amounts of indigo, adapting to a wide variety of climate and soils, thus making the dye widely available.
Early inhabitants and later, lower class people wore and used plain or natural color textiles because it took more sophisticated knowledge, time and effort to color them. Tannin based colorants and a wide range of yellow were more numerous and easily obtained from nature, but the color green was achieved only by over-dying yellow with blue. In many cases, purple was achieved by over-dying red with blue. Indigo yields a wide range of shades of blue, from pale azure to black blue-all beautiful in their own hue.
Indigo dye is a mechanical bonding dye which interacts with any natural fiber and forms a kind of coating over fiber which makes the textile stronger though weak against friction. Such is the attraction for denim Jeans.
