Our Enviro-Friendly Yellow Iron Oxide is a deep, rich ochre. DANIEL SMITH Enviro-Friendly Watercolours-the colours aren’t green, but the process is! To make these paints, we use pigments from the earth’s crust, obtained through a process known as Iron Oxide Recovery (IOR). This method removes coloured iron oxides that pollute mine water, cleaning the water so it can re-enter a receiving stream-and resulting in a cleaner natural environment. The recovered iron oxide is thoroughly washed, then used to create a trio of rich colours ranging in tone from a warm golden yellow to a deep red earth to a beautiful saturated dark brown with a bluish undertone.
