This color is popular in paints, lacquers, and decorating materials. Ultramarine was the finest and most expensive blue used by Renaissance painters. Our Gradient cursor has a particularly brilliant blue color and is lightfast, but it is not suitable to use outdoors because it weathers to a dull-blue powder. So this is an excellent choice to use as an Ultramarine Waves Gradient cursor pack. Ultramarine pigment was initially made by grinding lapis lazuli into a powder.
