A Geology of Color is an earth pigment book that contains 5 full, and reflective sections that will help guide you to identify, collect, and process rocks, dirt, and soil into artist-grade mediums.

For the last two years, I have immersed myself in documenting my processes and writing about my affinity for earth pigments. Today, I am sharing an exclusive preview for A Geology of Color, an earth pigment book that will be available for presale on October 18.

Once you have collected natural earth pigments, ochre will remind you when it’s ready to be processed into a pigment powder. Often, I don’t process rocks the moment they enter my studio—I tend to store them until their color moves me in some way.

Natural earth pigments range in color—from warm yellows, burnt reds, browns, earth greens, and even blue. These naturally occurring phenomena get their colors from minerals, and in the studio, they transform into the most beautiful artistic colors that reveal the hidden beauty of iron.
