Prussian blue ベロ藍(bero-ai): The first modern synthetic pigment, Prussian blue was an accidental discovery made around 1704–6 by chemist Johann Jacob Diesbach with the help of alchemist Johann Conrad Dippel. Composed of ferric ferrocyanide, this synthetically produced pigment yields a vivid blue. Due to its high cost as an import from the West during the 1800s, it was used initially for paintings. By the end of the 1820s, this pigment was produced in China, thus making it affordable for use as a colorant for woodblock printing.

Prussian blue's bright, intense “true blue” color, fine particle size, and high tinting strength soon made it an indispensable addition to the printmaker’s palette, largely supplanting dayflower and indigo. This enabled an even, sharp printing as well as a greater range of tones especially when printing graduated color. It is thought that the introduction of this colorant into the printmaker’s palette stimulated Hokusai and Hiroshige to design the iconic landscape prints for which they are celebrated. Prussian blue is both lightfast and stable to moisture.

-<font size="3">'''[[Prussian blue]]''' 藍(''ai'')</font>: A natural dark blue dye obtained from ''Indigofera tinctoria'' plants native to India, Java, Peru, and other tropical areas. The use of indigo was first mentioned in Indian manuscripts in the 4th century BCE. In Japan, indigo was introduced from China in the 6th century. The dye is obtained from an indigo plant native to Asia, ''Persicaria tinctoria''. Indian indigo was imported at the beginning of the Meiji period (1868).

-Indigo and dayflower are the two blues used in Japanese woodblock prints until Prussian blue enters the palette in the 1830's. Indigo appears most frequently from the 1740’s onwards as a color mixed with orpiment to produce a variety of greens. As a single colorant, it appears as a comparatively dull blue color. Due to its poor tinting strength, a relatively large amount needs to be used during printing in order to obtain a good saturation of this color. Its texture is somewhat coarse which makes it difficult to execute graduated hues from dark to light. Unlike dayflower, it is stable to moisture but is prone to fading.
+Prussian blue's bright, intense “true blue” color, fine particle size, and high tinting strength soon made it an indispensable addition to the printmaker’s palette, largely supplanting [[:Category:Dayflower: Ukiyo-e colorant|dayflower]] and [[:Category:Indigo: Ukiyo-e colorant|indigo]].
