A very clean, transparent “emerald” green, with a high tint strength and excellent lightfastness. The full chemical name of this modern organic pigment is phthalocyanine green, and is sometimes called thalo green. Phthalo green is similar in hue to the traditional Viridian, which is not compatible with acrylic binders. Phthalo green can be blended with yellows to make bright “lime” greens. Phthalo blue and Phthalo green blended together make a clean, beautiful turquoise.
