Winsor & Newton Professional Watercolours are made from the finest pigments available in the highest concentration possible for maximum colour strength and clean colour mixing.
Their superbly smooth handling and superior transparency make these watercolours the paint of choice for many practicing watercolour professionals around the world.
For the absolute best performance possible consider coupling these superior watercolours with an equally high-quality Series 7 Sable Watercolour Brush.
Cobalt Blue is a clean blue pigment. It was discovered in 1802 by French chemist Louis Thénard as an alternative pigment to the expensive Lapis Lazuli blue pigment.
