The History of Color

c. 40,000 BCE

The First Palette: Earth, Fire, and Carbon

The earliest known use of color by humans dates to at least 40,000 years ago — possibly much earlier. The palette was determined entirely by what could be found in the ground: red and yellow ochre (iron oxides), charcoal black, chalk white, and manganese dioxide for darker marks. These four colors — red, yellow, black, white — are the entire chromatic vocabulary of the cave paintings at Lascaux, Altamira, and Chauvet.

What is remarkable is not the limitation but what was achieved within it. The artists of the Upper Paleolithic used these four pigments to create images of extraordinary vitality — horses, bison, mammoths — with a confidence of line and a feeling for form that required nothing more than the colors of the earth beneath their feet.

c. 3000 BCE

Egyptian Blue — The First Synthetic Pigment

Around 3000 BCE, Egyptian craftsmen discovered that heating a mixture of copper minerals, calcium, silica, and an alkali produced a vivid blue powder that could be ground into pigment. Egyptian blue was the first known synthetic color — manufactured deliberately rather than found in the ground.

It colored the walls of temples and the masks of pharaohs for three thousand years. When the Roman Empire fell and the knowledge of its manufacture was lost, blue became one of the rarest and most expensive colors in the European palette — a gap that would not be adequately filled until ultramarine was introduced from Afghanistan in the thirteenth century.

c. 1500 BCE

Tyrian Purple — The Most Expensive Color in History

Tyrian purple was extracted from the mucous glands of marine snails — primarily Murex brandaris — found in the eastern Mediterranean. Producing one gram of dye required thousands of snails, a process that involved crushing, boiling, and exposing to sunlight over days. The smell was reportedly appalling. The result was a dye of extraordinary permanence that actually deepened in color as it aged in sunlight.

The color was so expensive that Roman law eventually restricted its use to emperors and their families — giving rise to the phrase "born to the purple." When Constantinople fell in 1453, the knowledge of Tyrian purple manufacture was lost. It was not chemically replicated until the twentieth century.

c. 1200–1400 CE

Ultramarine — Ground from Lapis Lazuli

Ultramarine — ultramarinus, "beyond the sea" — was made by grinding lapis lazuli, a semi-precious stone mined almost exclusively in a single valley in Afghanistan. It was transported along trade routes to Europe, where it was worth more than gold by weight. The blue it produced was unlike anything else available: intense, stable, and with a depth that seemed to vary with the angle of light.

In medieval painting it was reserved for the robes of the Virgin Mary — not because blue was the color of purity but because it was the most expensive color the patron could commission, and the Virgin deserved the best. Painters were required to show their ultramarine to patrons before use, to prove they were not substituting a cheaper blue.

c. 1200 CE

Verdigris and the Green Problem

Green was one of the most problematic colors in the medieval painter's palette. Verdigris — made by exposing copper to acetic acid vapors — produced a vivid blue-green but was chemically unstable. It reacted with other pigments, darkened with age, and was toxic. Many medieval paintings show passages of green that have turned brown or black: lead white reacting with verdigris over centuries.

Alternative greens — malachite, green earth — were more stable but far less vivid. The absence of a reliable, vivid, stable green is one of the defining characteristics of medieval European painting. It is not that medieval painters had bad taste; they simply did not have the chemistry.

1704

Prussian Blue — The First Modern Synthetic Pigment

In 1704, Berlin colormaker Johann Jacob Diesbach accidentally produced a vivid blue while attempting to make a red lake pigment. He had used contaminated potash — contaminated with iron compounds from an alchemist's laboratory — and the result was an intense, stable, affordable blue that transformed painting.

Prussian blue spread across Europe within a decade. By 1720 it was available in London. It was the first synthetic pigment produced in the modern sense — its chemistry understood, its manufacture reproducible. Artists including Watteau and Canaletto adopted it immediately. It is still used today, and since the 1960s has also been used medically to treat thallium and radioactive cesium poisoning.

1856

Mauveine — The Accident that Changed Everything

In 1856, eighteen-year-old chemistry student William Henry Perkin was attempting to synthesize quinine — a treatment for malaria — from coal tar. He failed, and the residue left in his flask was a sticky brown mess. When he tried to wash it out with alcohol, the flask turned a brilliant reddish-purple.

Perkin recognized what he had: a synthetic dye. He patented it, left university, and built a factory. Mauveine — also called aniline purple, or simply "mauve" — became a fashion sensation. Queen Victoria wore a mauve gown to her daughter's wedding in 1858. The decade became known as "the Mauve Decade." And Perkin's discovery inaugurated the synthetic dye industry, which would produce hundreds of new colors over the following fifty years — including colors that had never existed before.

1860–1900

The Synthetic Revolution — A New Color Every Year

Following Perkin's discovery, the German chemical industry systematically developed synthetic dyes from coal tar derivatives. New colors appeared almost annually: magenta (1858), violet (1860), aniline black (1863), Congo red (1884), indigo (1897). By 1900, virtually every color that had been expensive and rare for millennia was available cheaply from a factory.

The consequences were enormous. Traditional dye industries collapsed — indigo farmers in India, madder growers in France — within a generation. Clothing became cheap and colorful. The visual appearance of cities changed as synthetic dyes moved into paint, ink, and eventually plastics. For the first time in history, ordinary people could afford to wear vivid, saturated color.

1936

Phthalo Blue and the Age of Reliable Color

Phthalocyanine blue — discovered accidentally in 1928 at a Scottish dye works and developed commercially by ICI in 1936 — was everything previous blues had failed to be: vivid, stable, cheap, lightfast, and available in enormous quantities. Together with phthalocyanine green (1938), it completed a palette that artists had been trying to assemble for centuries.

The twentieth century also saw the development of cadmium pigments (brilliant yellows and reds, though toxic), titanium white (brighter and more opaque than lead white), and eventually polymer binders that made acrylic paint possible. By 1960, an artist could buy a palette of colors more stable, more vivid, and more varied than anything available to Rembrandt or Vermeer.

1953

Television and the RGB Revolution

Color television, introduced commercially in the United States in 1953, established the RGB color model as the foundation of screen-based color. Three phosphors — red, green, and blue — could be combined to produce the appearance of any color within a defined gamut. The model was not chosen for its perceptual accuracy (it is not particularly accurate) but because it matched the biology of the human eye's three cone types closely enough to work.

The RGB model also established the first standardized color gamut: the range of colors a system could reproduce. This was the beginning of the idea that color could be precisely specified, transmitted, and reproduced identically across devices — an idea that had never previously been technically possible.

1996

sRGB — The Color Standard that Runs the Web

In 1996, HP and Microsoft jointly developed sRGB — the standard RGB color space — as a way to ensure that colors looked consistent across different devices: monitors, printers, cameras, browsers. Before sRGB, a color specified in a web page might look substantially different on different screens. After, the differences narrowed considerably.

sRGB defines a specific gamut — the range of colors it can represent — and a specific gamma curve. It became the default color space for the web, for Windows, and for most consumer cameras and displays. It is still the dominant standard today, though wider gamuts (Display P3, Rec. 2020) are increasingly used in professional and consumer displays.

Today

16,777,216 Colors — The Complete 24-Bit Palette

A standard 24-bit display can render 256 levels of red, green, and blue — 256 × 256 × 256 = 16,777,216 distinct colors. This is the palette that PIGMENTUM catalogues in its entirety. Every color has a page. Every color has a name.

This number is in some ways arbitrary — human vision can distinguish perhaps ten million colors under optimal conditions, but the relationship between distinguishable and displayable colors is complex. What is not arbitrary is what the number represents: the entire chromatic vocabulary of the screens on which most human visual experience now occurs. A Paleolithic painter had four colors. You have sixteen million.

What this timeline shows is that the history of color is not the history of color itself — which has always existed — but the history of human access to it. Each era had the colors it could afford to make. We are the first era to have all of them at once.
