A Multicolored Library of the World’s Ochre Pigments Archived by Heidi Gustafson

Washington-based artist and researcher Heidi Gustafson forages, processes, and catalogs natural mineral samples for the Early Futures Ocher Archive. Ranging in color based on its elemental structure, ochre is crushed into a powder and used in various applications from art to medicine. With over 550 samples, Gustafson’s ever-growing archive has become a collaborative project with contributions from archaeologists, scientists, and creatives from around the world.

As each sample enters the collection, it is labeled with a corresponding number. In a notebook, Gustafson records where the ochre is from, who sourced or collected it, any historic or contemporary uses, and other relevant information. Gustafson grinds the iron-rich ochre into pigments, which she sells to artists and also uses for her own work. Processed samples are added to glass vials and organized by region or dominate mineral type. Gustafson also considers the material for its artistic, spiritual, and scientific properties. “More importantly, I build a relationship to the materials,” she tells Colossal. “I’m trying to understand their unique behaviors, the microbial communities they host and support, their tonal ranges, their historical uses and many other diverse features.”

The archive was officially formed in 2017 when Gustafson relocated to the Pacific Northwest, but working with the material is more than a hobby or intellectual pursuit—it is a calling. After having a dream about ochre, she initially wrote it off. Other experiences and anxieties about climate change inspired her to research exactly what ochre was and what it was used for. “I realized that ochre and pigments were at the heart of art and aesthetic experience,” Gustafson tells Colossal, adding that the mineral has been linked to complex mental processing in modern homo sapiens. “Protecting ochre’s vast capacities and impact on human creativity, feels like Earth’s mandate to me,” Gustafson continued. “I didn’t ‘come up’ with the idea for this project, it came to me and I felt responsible to do my best to understand and listen to that call.”
