Prussian blue is a deep and mysterious blue paint that creates the most magnificent foliage greenery. I love its tonal ranges from a very dilute pale cool greeny blue to the full mass tone of near midnight blue black.

Prussian Blue

This blue paint was created by accident around 1706 by a chemist in Berlin by the name of Diesbach. Strangely,  Diesbach was actually trying to create a red color.

But some of his ingredients were contaminated and voila!  The happy accident of “Berlin Blue”  also now known as  Prussian Blue,  occurred.

I like his spirit…. turning those pesky accidents into assets!

 

 

Many Names

Prussian Blue has been called many names,  Berlin blue,  Antwerp,  Parisian blue are just some of them.

However,  you  know that it is really Prussian Blue if the tube label describes it Prussian Blue Pb27.

I discovered long ago,  that I actually owned about 5 tubes of the same colour!  Paint manufacturers (Winsor and Newton, Daniel Smith, Art Spectrum, Holbein, Maimeri, American Journey, and a host of other brands)  can name their paints  what they please. So, so it can be confusing to a new beginner!

 

 

Prussian Blue has been used for medical purposes oddly enough.   And it was  the traditional blue used for creating “blueprints” as well.

In ancient times the Egyptians used blue dye made from copper.

Later  in history the Europeans started using the plant Woad, to create blue dyes.  Then, merchants began importing Indigo from the Americas.

The problem was that the “good” Blue  –  Lapis Lazulis –  had become very difficult to get. It was extremely expensive,  so there was a desire to find cheaper ways to create blue dyes and paints.

 

Staining Pigment Prussian Pb27

It is a Stainer, it leaves a stain.

It will not lift off the paper 100% as will the Transparents.  But,  it does lift to about 50 – 80% which is usually adequate.

Prussian Blue pb 27  is non opaque. Its see through.

These 2 traits make it fantastic for glazing, for luminosity, and clarity.   It does not make  mud when mixing.

The fact that it is a Stainer, also means it makes a great addition to a “pouring” painting,  it will run and spread beautifully, to create fantastic organic flowing patterns and textures.

 

 

When Prussian Blue is applied adjoining an opaque, say Naples Yellow and then allowed to …creep up and into the yellow… you can get some wonderful effects.

 

I find Prussian Blue equally good in oils, watercolour, soft pastels.

In Acrylics,  Prussian blue is just a little under done for my tastes. Not quite the oomph of oils nor watercolours.  But, that’s just my opinion.   I still use Prussian in acrylics,  its just that they don’t perform at a 10 level.  Maybe 8.5 or so.

Goals

My primary objectives for choosing Prussian Blue when I’m selecting my colours

#1  to create and mix a great range of  foliage greens

#2 to create some intense darks

#3 to help create textures,runs and patterns within the wet paint areas

 

 

Prussian Blue has lovely possibilities – traditional landscapes, to abstracts, pouring paintings, to botanical art. It is a colour that does very well in pretty much all the mediums, proving the rich intensity of tone that is its hallmark.

Prussian Blue is one of my Core group of 7 paints, in all my mediums I use. I really enjoy its complexities and tones.

 

Don’t be afraid of the Stainers!
