[1] It is a bright, high intensity colour used in oil and acrylic based artist's paints, and in other applications.

Due to the presence of strongly electronegative chlorine substituents, the absorption spectrum is shifted from that of the parent copper phthalocyanine.

Phthalo green is highly stable and resistant to alkali, acids, solvents, heat, and ultraviolet radiation.

Due to its stability, phthalo green is used in inks, oil paint, coatings, and many plastics.

Copper phthalocyanine green 36 is a variant where some of the chlorine atoms are replaced with bromine.
