Azurite is an inexpensive greenish blue that is extremely stable under normal conditions and has chemical similarities to the green pigment malachite. Its greenish tints become more intense when mixed with oil. A gentle heating of Azurite produces the deeper blue pigments used in Japanese painting techniques.
Azurite has good permanence in oil and tempera media. It is unaffected by light, though it can darken if exposed to sulfur fumes.
Azurite is highly toxic if ingested and moderately toxic if inhaled.
Azurite gets its name from the Persian word lazhward, meaning blue. It has been in use since the 25th century BC, during the Fourth Dynasty of Egypt. Azurite was the most important pigment in European painting from the Middle Ages to the Renaissance, though it was often confused with Lapis Lazuli and overshadowed by Ultramarine. Azurite was the characteristic color of the sky in Renaissance paintings, but was replaced by Smalt in the 17th century and Prussian Blue in the 18th century. Because it is toxic, and because the hue can easily be produced using other pigments with desirable properties, use of azurite has become uncommon.

Phthalo Green is a transparent, cool, bright, high intensity color used in oil and acrylics. It comes from a Phthalocyanine Blue pigment where most of the hydrogen atoms have been replaced with chlorine, forming highly stable molecules. It has similar pigment properties and permanence to Phthalo Blue. It is slow drying and an excellent base color for mixing a range of bright greens. Phthalo Green is considered a very good alternative to Viridian because it is intense and mixes well and can be used to emphasize mineral colors in various tints. However, its tinting strength is very high, so it can overpower other colors. This pigment most closely resembles the discontinued and toxic Verdigris.
Phthalo Greens are completely lightfast and resistant to alkali, acids, solvents, heat, and ultraviolet radiation. They are currently used in inks, coatings, and many plastics due to their stability and are considered a standard pigment in printing ink and the packaging industry.
Phthalo Green has no significant hazards, but it contained PCBs (polychlorinated biphenyls) until 1982.
This bright blue-green was developed in 1935 and has been in use since 1938.
