About Prussian Blue Color

Prussian Blue was an early modern synthetic pigment whose arrival expanded the working palette of painters and printmakers. By the early nineteenth century it had reached Japanese print production; technical analysis of Hokusai’s Great Wave identified it alongside traditional indigo rather than as a simple one-for-one replacement.

That layered use is a useful design lesson. Prussian Blue can work as a deep structural blue, while nearby indigo or lighter blue tones add depth without reducing the palette to one dark block. Its historical paint behavior and a CSS swatch are different media, so matching the HEX does not recreate ink layering, paper, or pigment concentration.

This page defines a stable digital Prussian Blue reference and does not claim to reproduce a particular historic paint or print impression.
