Thanks for your insights Parka. I agree with your assessment of the Kremer Cobalt Dark Blue. Like most Kremer watercolours, however, it doesn’t mix well with other pigments. The granulation of Holbein’s Ultramarine Blue Deep is extraordinary; it also mixes well with other pigments to make evocative greys and rich purples. In contrast, I have found that Holbein’s Cerulean Blue has the least dramatic granulation of the Ceruleans I have tried (including D. Smith, Windsor & Newton, and Sennelier).
