My favourite blue

Prussian Blue:

A colour I keep returning too and so I consider it my favourite blue. When used as a glaze it adds depth to a painting, as an under layer it helps create atmosphere a foundation to build on. The reddish tint within the blue makes it warm and inviting. It always lifts my mood when I am painting with it.

Prussian blue was first synthesized about 1704 by the reaction of salts of iron in the +2 oxidation state (ferrous salts) with potassium ferrocyanide; (https://www.britannica.com/technology/Prussian-blue)
