Mingei International Museum’s Bold, New Exhibition Blue Gold: The Art and Science of Indigo Celebrates Magical Transformation of Plants into Color
On view until March 16, 2025
It’s the color of ocean tides, a starry dusk sky, and a pair of vintage Levi’s. Indigo blue is all around, but harnessing this hue is a complex feat of chemistry and botanical transformation. The exhibition Blue Gold: The Art and Science of Indigo, which opened at Mingei International Museum in Balboa Park on September 14, 2024 combines art, craft, science, and history to explore this color’s past and present. The show is among more than 70 exhibitions and programs presented as part of Getty’s 2024 PST ART initiative returning in September with its latest edition, PST ART: Art & Science Collide. This landmark regional event explores the intersections of art and science.






Blue Gold explores the extraordinary process of transforming plants into pigments. Indigo has a long and multifaceted history of cultivation, production, and distribution that will resonate with anyone who loves the color blue and shares a curiosity for the chemistry and indigenous knowledge behind its process. Blue Gold will present indigo as a compelling manifestation of art and science. Over 180 works representing 30 countries include featured objects from Mingei’s permanent collection, works on loan from national and international organizations, and commissioned work created for this exhibition by gifted artists and craftspeople, including Christina Kim and Porfirio Gutiérrez, among others.
The indigo dye process involves grinding leaves from the Indigofera plant into powder, boiling the powder into a rich liquid, and fermenting it to complete a transformative chemical reaction. Indigo dye has been used for thousands of years, spanning all continents, cultures, and methods. From ancient Mesopotamia to present-day West Africa, indigo has an expansive heritage that transcends that of other dyeing methods, even in contemporary times. Indigo’s beauty and ubiquity have eclipsed the unpleasant realities of its growth and manufacture, including hard labor and pollution and its association with colonialism and slavery. This exhibition highlights the importance of nuanced conversations that celebrate beauty without skipping over a grim past.
From 7th century textiles to 20th century kimonos, the exhibition not only highlights brilliant textiles and works of contemporary art and craft from Asia, Africa, Europe, and the Americas, but also examines indigo’s many other uses in the realms of science, spiritual practice, and more.







Mingei Director of Exhibitions and Chief Curator, Dr. Emily Hanna, notes that “Indigo, a deep blue dye derived from green plants, has been used by cultures across the world. The title of this exhibition alludes to its value as a commodity, but also elevates its aesthetic worth.”
