Chemistry of Plant Fibers and Dyes

What is a dye, and what distinguishes it from a mere pigment? What is typical of plant fibers as compared to animal fibers?This class is a gentle introduction to the chemistry of color and to the special structures of colorful plant substances and those that can be used as dyes on fibers. (No previous chemistry knowledge required, but always helpful.) A lecture introduction with many pictures will be followed by a walk in the Garden to view live fiber and dye plants.
