Winsor & Newton Professional Watercolour - French Ultramarine
French Ultramarine is a rich transparent blue. It was created by French chemist Guimet in 1828 as a synthetic but chemically identical alternative to the expensive pigment derived from Lapis Lazuli.
Professional Watercolour is recognised for using only the purest pigments to ensure quality and permanence. Formulated using the highest quality production methods to achieve optimal pigment dispersion, the Professional Watercolours' unrivalled transparency means every wash will remain vibrant and luminescent.
