From the perspective of the type of pigment

Phthalocyanine blue belongs to the phthalocyanine pigment in the organic pigment system. Ultramarine blue belongs to the blue pigment in inorganic pigments. Therefore, phthalocyanine blue does not contain heavy metals, and ultramarine blue contains trace amounts of heavy metals. But ultramarine blue is different from other inorganic blue pigments, such as iron blue. It contains very small amounts of heavy metals and belongs to non-toxic inorganic blue pigments.

From the performance of the pigment

Phthalocyanine blue has strong tinting power, but its light fastness and weather resistance are not as good as ultramarine blue. Ultramarine blue has strong hiding power and good resistance, but its tinting power is not as good as phthalocyanine blue. The performance of ultramarine blue that has to be mentioned is whitening. When used in yellow products, it can effectively remove the yellow light in yellow products and make them whiter.

From the point of view of the use of pigments
