Winsor & Newton Professional Watercolour - Indigo
Indigo is a deep blue pigment that can range from dark black to pale blue. Originally extracted from plants similar to blue woad used by the ancient Britons, it was synthesised in 1878 in Germany. It is one of the oldest blue pigments used universally.

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.
