Anthraquinone Blue Professional Watercolour is prepared using the synthetic organic pigment, 6,15-dihydroanthrazine-5,9,14,18-tetrone. The pigment has been selected for its purity, light fastness and intense blue hue, making it ideal for use in A J Ludlow’s Professional watercolour range.

First patented in 1901 as the first anthraquinone vat dye, the pigment has very good light fastness and transparency and is often used as an alternative to natural indigo (albeit with a small addition of carbon black). As a vat dye, it is used to colour cotton and is known as C.I. Vat Blue 4, whilst the pigment is sometimes called indanthrone blue and indanthrene blue.
