Dr. Ruth Siddall tells us about pigments, natural dyes, lake pigments and how you can make your own plant based pigment from onions! We discuss colours and their origin in nature and their relationship in some cultures. We also chat about the Pigment Compendium, World Pigment Day and safety of using pigments and much more!
