The science and art of plant colour

This hands-on workshop brings together science and creativity to explore the world of natural dyes – co-taught between the Curator, who specialises in the science of plant pigments and our artist in residence. Participants will work with plants collected from the botanic garden and investigate the chemistry behind their colours, focusing on key pigment groups such as flavonoids, which contribute brilliance and UV protection; betalains, known for deep reds and purples; indigoids, responsible for classic blue tones; and carotenoids, which offer vivid yellows and oranges. Guided step by step, attendees will learn how to process these plants into dyes, inks, and paints, drawing on traditional techniques and recipes inspired by historical manuscripts and cultural practices. By the close of the session, participants will leave with beautifully coloured samples and a deeper understanding of the relationship between nature, chemistry and artistic expression.
