(aka Indanthrone Blue)
Pigment Light Fastness Rating: I Excellent
Anthraquinone Blue is a very dark, semi-transparent blue. It has a moderate tinting strength that is easily controlled when creating mixes. This blue is reminiscent of the night sky when extended with wax medium, maintaining lots of depth and richness as well. Even though has a slightly reddish cast it is equally suited to mixing deep purples as well as deep greens. When mixed with white it tends to grey out to a "navy", and if bluish grey is what you are looking for, try mixing it with any of the umbers and wax medium. It has completely different properties than the Phthalo Blues, Ultramarine or Prussian Blue, making it a necessity to our paint line.
