Prussian Blue: The Historic Hue Missing from Most Modern Acrylic Paints

The Accidental Creation of Prussian Blue and Its Early Impact

Prussian Blue, one of the most iconic and historically significant pigments, has a fascinating origin story that combines science, artistry, and a touch of serendipity. Its creation in 1704 marked a pivotal moment in the history of pigments, ushering in a new era of color in European art. This deep, rich blue hue was not born from meticulous planning, but rather an unexpected accident that forever changed the world of painting and printmaking.

The tale begins with a pigment manufacturer named Diesbach, working in Berlin. At the time, he was attempting to create a red dye using a combination of potash, crushed cochineal insects, and iron sulfate. The process was going smoothly until Diesbach found himself in a predicament had run out of potash. In search of more supplies, he visited a local pharmacist named Johann Konrad Dippel. Little did Diesbach know that the potash Dippel provided was not what he expected. It was contaminated with dried cattle blood, a seemingly inconsequential change that would set the stage for one of the most important discoveries in pigment history.

Instead of the anticipated red dye, the mixture resulted in a brilliant, vibrant blue. Diesbach had unwittingly created a new pigmentPrussian Blue. Initially named Berlin Blue, the pigment was kept secret for a time, with Diesbach and Dippel quietly refining the formula. However, by 1724, English chemists managed to reverse-engineer the pigment’s chemical composition, unveiling its secret to the world. This discovery would eventually lead to the downfall of Diesbach and Dippel’s business, as they lost control over the production of their groundbreaking invention. Dippel, ever the eccentric figure, moved on from the world of pigments and delved into bizarre pursuits, including attempting to market himself as the discoverer of the "elixir of life." Despite his odd claims, Dippel's role in the creation of Prussian Blue remains an indelible part of history.

Prussian Blue: A Game-Changer in Art and Chemistry

The invention of Prussian Blue was a groundbreaking achievement in the world of art. Not only was it the first synthetic blue pigment discovered in over 3,000 years since the ancient Egyptians developed Egyptian Blue, but it also presented artists with a rich, durable, and affordable alternative to the rare and expensive natural blues like lapis lazuli. Before the creation of Prussian Blue, the only available blue pigments were derived from semi-precious stones or minerals, which made them prohibitively costly for many artists. Lapis lazuli, for example, was mined in Afghanistan and was extremely rare and expensive, making it accessible only to the wealthiest patrons and artists. The discovery of Prussian Blue democratized the color blue, making it more accessible to a wider range of artists, from amateurs to professionals.

The impact of this new, vibrant pigment on European art was profound. During the Baroque and Rococo periods, Prussian Blue quickly became a favorite among artists, as its deep, intense hue added a richness and sophistication to their works.

The Challenges of Incorporating Prussian Blue in Acrylic Paints

Prussian Blue, a pigment with a rich history and deep, intense color, is a staple in the world of oil paints and watercolors. However, it remains conspicuously absent in many acrylic paint lines. This absence is primarily due to the complex challenges of adapting this specific pigment to the unique properties of acrylic mediums. Acrylic paints, which utilize polymer emulsions as binders, present a fundamentally different environment compared to oil or watercolor paints, making Prussian Blue particularly difficult to incorporate.

The first and most significant challenge comes from the chemical nature of acrylic paint. Acrylic mediums are known for their relatively high alkalinity, with pH levels that typically range from 8 to 9. On the other hand, Prussian Blue is known to be sensitive to alkaline substances. The pigment’s chemical structure is not well-suited to endure exposure to high pH environments, which causes it to degrade, lose vibrancy, or undergo undesirable color shifts. This incompatibility often results in the pigment breaking down over time, leading to a reduction in its overall stability and causing the vibrant blue hues to lose their depth and intensity.

Another obstacle to using Prussian Blue in acrylic paints is its reaction with the binders typically used in acrylic formulations. Acrylic polymer emulsions, which are designed to provide the flexibility, durability, and adhesion that acrylic paints are known for, do not offer the ideal environment for Prussian Blue. The high pH levels in these emulsions can cause the pigment to destabilize, leading to fading and diminished color quality. For this reason, artists have historically turned to other pigments that are better suited to the chemistry of acrylic paints, often sacrificing the distinctive qualities of Prussian Blue in favor of more stable alternatives.

Lightfastness and Fading Issues in Acrylic Paints

Prussian Blue’s sensitivity to light is another significant challenge that complicates its use in acrylic paints. While the pigment’s striking color has made it a favorite among artists for centuries, its lightfastness has always been a concern. Prussian Blue tends to fade more quickly when exposed to light, especially when mixed with white pigments. This phenomenon is particularly troublesome for acrylic paints, which are highly valued for their long-lasting durability and resistance to fading. Acrylics, unlike traditional oil paints, are designed for longevity and are often chosen by artists precisely for their ability to resist fading over time.

The fading issue with Prussian Blue is a result of the pigment's unique chemical composition. Although it has been refined over the years to improve its stability and lightfastness, it remains prone to fading under prolonged exposure to sunlight. This issue is particularly apparent in mixed colors where Prussian Blue is combined with white or light hues. The result is often a noticeable change in the vibrancy of the color, which can compromise the overall appearance of a painting, especially over time. For artists who seek both longevity and vibrancy in their work, this fading tendency makes Prussian Blue less desirable in modern acrylic formulations.

In response to these challenges, some paint manufacturers have taken significant steps to improve the lightfastness of Prussian Blue in acrylics. Advances in pigment processing and the development of new acrylic formulations have made it possible for some brands to offer Prussian Blue paints that are more stable and resistant to fading. However, these improved versions are still relatively rare compared to more commonly used pigments, such as Phthalo Blue, which is often favored for its stability and strong color retention.

The Development of Alternative Prussian Blue Formulations

Despite the challenges posed by its chemical incompatibility and fading tendencies, there has been a growing interest in replicating the unique qualities of Prussian Blue within the world of acrylic paints. Some acrylic manufacturers have succeeded in creating Prussian Blue formulations that retain much of the pigment’s deep, intense color while addressing issues related to stability and lightfastness. One such example is Matisse Derivan’s range of acrylic paints, which includes an authentic version of Prussian Blue (PB27). This formulation has been carefully engineered to ensure that the pigment performs well in the more alkaline environment of acrylic paints while also exhibiting improved lightfastness.

Matisse Derivan’s Prussian Blue acrylic paint is a rare and valuable addition to the acrylic paint market. The manufacturer has invested in research and development to ensure that this particular formulation remains stable, even when exposed to light over time. This makes it a desirable option for artists seeking to use authentic Prussian Blue in their acrylic works without sacrificing the long-lasting durability for which acrylic paints are known.

However, the availability of genuine Prussian Blue in acrylics remains limited. As a result, many manufacturers have opted to create alternative formulations that replicate the color of Prussian Blue without using the original pigment. These alternatives often combine a mix of other pigments, such as Phthalo Blue, Carbon Black, and Dioxazine Violet. These mixtures can achieve a similar color to Prussian Blue, but they do not replicate its full range of characteristics. While the resulting hue may resemble the deep, inky tone of Prussian Blue, it lacks the same complexity and depth, which are among the defining traits of the original pigment.

The use of alternative formulations is a practical solution for artists who want to incorporate the look of Prussian Blue in their acrylic works but are willing to accept some variation in the color’s overall tonal qualities. These blends offer an easier and more stable way to replicate the appearance of Prussian Blue without the risk of instability, but they do not fully capture the unique attributes of the pigment. For artists who prioritize authenticity, however, these alternatives may fall short of their expectations, as they cannot fully emulate the distinct undertones and depth that make Prussian Blue so special.

Prussian Blue's Future in Acrylic Paints

As the demand for more diverse and high-quality acrylic paint formulations continues to grow, it is possible that we will see further innovation in the development of Prussian Blue acrylics. While the challenges associated with the pigment’s instability in high-pH environments remain, ongoing research in both pigment chemistry and acrylic binder technology may lead to breakthroughs that allow for the wider use of Prussian Blue in acrylic paints. Artists who have long yearned for an authentic Prussian Blue in their acrylic palettes may soon find more options available to them, allowing for a deeper exploration of this rich and captivating pigment.
