Prussian Blue

Prussian Blue

A deep, intense blue with a rich history. First created in 1704 by German chemist Diesbach, Prussian Blue was the first modern synthetic pigment and quickly became a valued alternative to the more costly genuine Ultramarine. With its inky depth and strong tinting strength, it remains a staple for artists seeking drama, contrast, and atmosphere.
