Colours in great artworks carry hidden stories from toxic pigments to accidental discoveries that reshape how we read masterpieces. Kelly Grovier’s work traces these narratives, revealing how hues like Prussian Blue and vermilion link artists across centuries and alter the meaning beneath familiar canvases.
Pigments aren’t just materials; they are historical actors. An alchemist’s mistake in early 18th-century Berlin gave rise to Prussian Blue, a color that would unite Hokusai’s The Great Wave and Picasso’s The Blue Room and transform the palettes of Monet and Degas. Such origins and the social histories of pigments unlock fresh layers in works we thought we knew.
How pigments shape art
Accidents, alchemists and new blues
- Prussian Blue: Discovered around 1706 when Johann Konrad Dippel’s failed concoction was repurposed by a dye-maker, producing a deep blue that rivalled costly ultramarine. Its affordability and brilliance democratized blue in art, appearing in East Asian prints and European modernism alike.
Toxicity and technique
- Vermilion and other reds: Derived from mercury sulfide, vermilion produced vivid reds in works from Vermeer to Munch but carried health risks for painters. Lead white, cinnabar and other traditional pigments also posed dangers, influencing studio practice and conservation needs.

H3: Hidden messages and provenance
- Material stories can expose unexpected links — trade routes, colonial supply chains, and even cultural attitudes. The use of a particular dye or mineral can point to a workshop’s network, a patron’s wealth, or a political context otherwise invisible in the image alone.
Conservation and interpretation
- Scientific analysis (X-ray, pigment microscopy, spectroscopy) uncovers underlayers, revisions and earlier compositions, helping conservators preserve works and historians reinterpret an artist’s intent.
