Heidi Gustafson is an artist and writer, but is perhaps best known as an ochre whisperer. Based in the Pacific Northwest, she curates the Early Futures Ochre Archive, a growing collection of over 600 samples of ochre from around the world. Her debut book, Book of Earth: A Guide to Ochre, Pigment, and Raw Color, explores our ancient relationship with color, creativity, and the land. Heidi is dialed in on the lesser known world of minerals upon which our world revolves. It's a discipline that bridges science, anthropology, spirituality, history, poetry, and captivating photography.
