Ultramarine Blue 29 (PB29) is a synthetic inorganic pigment used in paints, plastics, inks, and cosmetics due to its vibrant blue color, lightfastness, and non-toxicity.
It is a complex sodium aluminum silicate sulfate with sulfur radicals, giving it its distinctive violet-blue hue, and is a modern, affordable replacement for the natural lapis lazuli pigment.
