Book excerpt: This updated 2nd edition features a revised chapter. True Colors is about artists who create color from natural materials and about the historical importance and environmental sustainability of this practice. Deep conversations with 26 artisans from every part of the globe reveal their wisdom, traditions, and know-how—and suggest that we ignore what they know at our peril. Traditional approaches to making color offer sustainable options to a fashion system badly in need of them and memorable cultural narratives to a world hungry for beauty and spirituality. True Colors provides an immersive visual experience and an inspiring travelogue of personal stories and practical information from artists who are leaving their mark on the world.
