Art Spectrum® Indigo Blue is a deep purple between blue and violet on the spectrum. Here it is based on a combination of Ultramarine and Prussian blue. The colour has been used since ancient times when both the ancient Greeks and the Romans sourced it from India where it was made from the plant Indigofera Tinctora .
Its name in Greek, ινδικόν (or ‘Indikon’), simply means ‘dye’.. In accordance with proven traditional methods of production, all Art Spectrum® Artists’ Watercolours are carefully stone milled to enhance the individual brilliance of each selected permanent pigment and to maximise its handling qualities. Successful watercolours depend on selecting the best quality paper, the permanence and brilliance of the pigments and the use of a wide variety of quality brushes.
