Color is beautiful and, often, toxic. This DW film follows three people working on that contradiction from different angles. In Cambridge, biologist Jim Ajioka and colleague Orr Yarkoni run a start-up trying to replace the dyes used in textile manufacturing, an industry that, as Ajioka puts it, dumps its wastewater straight into rivers in countries like Bangladesh, China, and India; their alternative uses microbes instead of chemicals like mercury, lead, and chromium. In the Allgäu region of Germany, David Kremer mills paints from stone and mineral according to traditional methods, supplying restoration pigments to the Louvre and the Prado, and the film follows him to Greece hunting for a mine that produced pigment in antiquity. In the Netherlands, color consultant Jeanet Marit Herbst redesigns hospital interiors, arguing with clinical partners that the right palette lowers blood pressure and mood-related medication use. The film moves between a textile lab, a paint mill, a Greek quarry, and a clinic without losing the thread connecting them.
