The brilliance, transparency, and purity of color are unparalleled compared to any other watercolor. Since 1832, when Henry Newton and William Winsor introduced the first moist watercolors to the world, much of our reputation for supreme quality has stemmed from the Professional Water Color range. Our Professional Water Color range continues to be formulated and manufactured according to our founding principles. Each color within this wide and balanced spectrum of 96 colors has been selected and formulated to offer the greatest choice so that artists can create a unique palette that best suits their work.

Cobalt Blue, a clean blue pigment, was discovered in 1802 by French chemist Louis Thenard as an alternative to the expensive Lapis Lazuli blue pigment. It is one of the many options within our range that provides the highest possible permanence and unparalleled quality. The variety of pigments available makes it the finest watercolor offering the widest choice of pigments. Cobalt Blue falls under Series 4, Color Code 178, and has a Color Index of PB 28.
