Field's Chromatography: or Treatise on Colours and Pigments as Used by Artists

In Short

This book is a comprehensive, analytical guide to the chemistry and behavior of artists' pigments. It categorizes colors systematically—from the primaries of yellow, red, and blue through complex tertiaries and neutrals—while rigorously evaluating their durability, lightfastness, and chemical compatibility. Written with the precision of a laboratory report and the experience of a master colorist, it serves as an indispensable reference for understanding why some paintings endure for centuries while others fade into obscurity. Its legacy lies in bridging the gap between scientific investigation and the practical application of paint.

The Story

The narrative of the book is one of systematic exploration, moving from the abstract theory of color relationships toward the granular, often treacherous world of physical pigments. It begins by establishing a fundamental philosophy: color is not merely an optical phenomenon but a material reality. The author posits that the artist must act as both visionary and chemist, for the longevity of a work is dictated by the chemical stability of the substances applied to the canvas.

The journey continues into the nature of "fugacity"—the tendency of colors to vanish or alter over time. The author dispels the myth of permanence, demonstrating that even the most celebrated pigments are subject to the ravages of atmosphere, foul air, and incompatible mixtures. He introduces the reader to the "neutral" foundation of painting, emphasizing that white is not just a color but an instrument of light, capable of dilution or degradation depending on the substances with which it is paired.

As the book progresses into specific classifications, it turns into a meticulous catalog of ingredients. Each chapter examines a pigment’s origin, its behavior in both water and oil, its tendency to react with other minerals, and its susceptibility to decay. The author provides vivid examples of the "bad actors" on the palette—pigments that are brilliant in the pot but disastrous on the canvas—while championing those that possess true longevity.

The arc concludes with the complex tertiary and semi-neutral colors, which the author argues are more essential to the truth of nature than the primary hues. He explores the subtle grays, browns, and citrines that define the shadows and atmospheric depths of a landscape. By the end, the reader is left with a sobering but empowering lesson: the act of painting is a constant negotiation with chemical forces. The author does not offer a simplified list of "best" colors; instead, he provides the intellectual tools to test, select, and combine materials with an awareness of their potential for transformation. It is a transition from the artist as a mere user of color to the artist as an informed guardian of their own legacy.

How It Unfolds

The philosophy of color The opening chapters define color as a relative concept, arguing that its beauty is inextricably linked to its durability. The author asserts that the artist must understand the material composition of their tools to master the art of permanence.

The science of pigments The middle section establishes the criteria for quality, distinguishing between reliable substances and those that are prone to fading or chemical poisoning. Here, the author introduces the crucial notion that time and fire act upon pigments in similar, destructive ways.

The classification of hues The bulk of the text categorizes pigments from the primary triad through the subtle, earthy tertiaries. Each entry acts as a standalone report on the chemical identity and "habits" of a specific color.

The cautionary conclusions The final chapters address the neutrals and the complexities of mixing, warning against the adulteration of pigments. The author concludes by emphasizing that true mastery requires a refinement of taste that only comes from deep study of how pigments actually perform in the studio.

The People

The book is driven by the voice of the author, an observant and highly experienced colorist who approaches his subject with the rigor of a scientist. He is a man of strong opinions, often dismissive of "spurious" or "inferior" commercial products that lead to the ruin of fine art. He acts as a mentor, guiding the reader through the laboratory of the studio, where the "artist" is defined as a person who must balance aesthetic intention with chemical caution. The "old masters" are frequently invoked, not as distant idols, but as practitioners whose works provide the ultimate evidence of pigment stability. His tone is that of an expert who has seen the "foul air" of a city destroy a vibrant canvas and is determined to prevent his readers from suffering the same professional heartbreak.

In Its Own Voice

"As colour itself is relative, so is durability of colour relative; for the reason that all material substances are changeable and in perpetual action and reaction, no pigment is so permanent as that nothing will alter its colour."

The author sets the stage for his technical analysis by reminding the reader that all physical objects, including paint, are subject to the relentless passage of time.

"To understand and relish the harmonious relations and expressive powers of the tertiary colours, require a cultivation of perception and a refinement of taste for which study and practice are needed."

This statement highlights the author’s belief that the most profound effects in painting are found in the subtle, broken colors of nature rather than in simple, primary hues.

What It's Really About

At its core, this book is about the tension between human intention and material instability. It argues that the artist’s vision is at the mercy of the physical world. The fundamental question beneath the technical advice is: How can we create something that lasts? The book explores the ethics of artistic production, suggesting that using unstable pigments is an act of carelessness toward the future. It treats painting as an exercise in chemistry where the "truth" of a color is defined by its ability to resist decay. By moving beyond the surface appearance of a painting, the author reveals that artistic success relies on a profound, almost scientific respect for the elements themselves.

Why Read It Today

Readers who have ever felt the frustration of a painting changing, yellowing, or cracking after it leaves the easel will find this book deeply validating. It is not a "how-to" manual for painting techniques, but a "why-not" guide for material selection. It feels like stepping into a nineteenth-century apothecary, where the air is thick with the smell of oils, minerals, and deep, technical knowledge.

The book is challenging; it is dense with chemical names and specific, often antiquated, pigment designations. Readers should be prepared for the author's uncompromising standards and his occasionally haughty dismissal of modern shortcuts. However, the reward is an unparalleled intimacy with the materials of art history. You will walk away with a permanent change in how you look at the museum wall—you will no longer see just a sunset or a portrait, but the chemical resilience (or failure) of the pigments that compose them. For the serious student of art, the historian, or the curious hobbyist, this work offers a rare, grounded clarity that cuts through the marketing of modern art supplies, reminding us that every color carries a history and a future.
