Indanthrone Blue is redder than both Prussian and Phthalo Blue, yet more subdued than Ultramarine. It offers complex grey subtleties in a tint. What is unique about Indanthrone Blue is its neutrality. Its virtue is not its beauty, but its usefulness. As a chromatic black, it enhances the saturation of juxtaposed colors.
