Phthalocyanine green G, which has many commercial names, is a synthetic green pigment from the group of phthalocyanine dyes, a complex of copper(II) with chlorinated phthalocyanine. It is a soft green powder, which is insoluble in water.[1] It is a bright, high intensity colour used in oil and acrylic based artist's paints, and in other applications.
