Phthalo Green (Phthalocyanine Green) is a modern synthetic giant in the world of color, renowned for its incredible intensity and permanence. Born from the same chemical breakthrough that created Phthalo Blue, this pigment was first introduced to the artist market in 1938, shortly after its blue counterpart. It is created by chlorinating copper phthalocyanine, resulting in a deep, transparent, and cool-toned green.

Historically, the arrival of Phthalo Green was a revolution. Before the 1930s, artists struggling for a vibrant, stable green often had to rely on Emerald Green (which was highly toxic, containing arsenic) or Viridian (which, while stable, is much less intense and has weak tinting strength). Phthalo Green effectively rendered the dangerous Emerald Green obsolete, offering a non-toxic, lightfast alternative with vastly superior mixing power.

In art, its use is defined by its potency; it is often described as a “bully” on the palette because a tiny amount can overwhelm a mixture. However, this high tinting strength makes it indispensable for contemporary painters. It was embraced by mid-century abstract expressionists like Jackson Pollock and Francis Bacon for its visceral, piercing quality. Today, it is a standard staple for landscape and seascape artists, who prize its transparency for glazing and its ability to mix with yellows and earth tones to create an infinite variety of natural, lush greens that earlier masters could only dream of.
