Made in the USA About the Brand: Natural Earth Paints was founded in 2009 by a soon-to-be mom who had to work full-time prepping for a large solo art exhibition. She realized that she didn't want to expose her baby to all the toxic chemicals found in traditional paints. And so Natural Earth Paints was born. Drawing inspiration from the Renaissance masters, the growing green company uses all-natural materials to create magnificent pigments and sustainable, eco-friendly art supplies.
