Color has played an important role in human history, from prehistoric cave paintings to modern day design. But when did humans first start creating pigments and dyes to color their world? The origins of synthetic colors are ancient, emerging across different cultures worldwide. By examining the archeological and historical record, we can piece together an understanding of how and why color came to be manipulated and manufactured.
Early Use of Color
Some of the earliest evidence of human use of color comes from prehistoric cave paintings dating back over 40,000 years. Early humans used natural pigments like red and yellow ochre, charcoal, and iron oxides to create cave art. While these pigments were sourced from the environment, their application to cave walls represents an early attempt by humans to add color to their surroundings.
Other prehistoric uses of color include decorative beads, body painting, and dyed textiles. Red ochre pigments used in burials in Upper Paleolithic sites suggests colors had ritual and symbolic functions for early humans. By grinding and mixing pigments, they transformed raw materials into new substances for creative expression.
Ancient Synthetic Pigments
It was during the Ancient world that production of synthetic pigments and dyes really accelerated. In Egypt, blue and green pigments were being manufactured from copper minerals as early as 2500 BC. The famous Egyptian Blue paint used ground limestone, sand, copper, and alkali to create a vivid blue hue for tomb paintings and artifacts.
The ancient Chinese also produced synthetic pigments, with the earliest dates for manufactured vermillion and Chinese purple found around 1000 BC. Vermillion or cinnabar came from mercury sulfide, while Chinese purple was a mix of barium copper silicate that produced a range of violet to reddish purple tones.
The Ancient Greeks and Romans continued developing new pigments and mastering color techniques. Greek vase painting used black, yellow, orange, red, purple, and white pigments, while innovative Roman glassmaking produced the vivid intense blues and greens associated with this civilization.
Across the ancient world, new trade routes spread materials and knowledge that accelerated the production of synthetic pigments. The earliest manufactured colors were toxic, sourced from minerals like lead, arsenic, and mercury. But vibrant and stable colors made accessible new worlds of expression.
Middle Ages and Renaissance Pigments
During the Middle Ages and Renaissance, pigment production increased as painterly arts grew in prominence. European monasteries became centers of pigment production, experimenting with formulas for ultramarine, verdigris, and lead-tin yellows.
The 15th century saw trade spread new pigments like crimson lake (a red dye from insects) and smalt (ground blue cobalt glass). Oil painting also expanded the pigment repertoire, allowing rich vivid hues. The discovery of the New World opened up new pigment sources like cochineal (red dye from American insects).
By the Renaissance, mastering color and technique was a means for painters to demonstrate their skill. Painters like Van Eyck, Michelangelo and Raphael pushed painting to new technical and creative heights through their command of color.
Modern Synthetic Pigments
Modern synthetic pigments emerged from 18th century chemistry advances. In 1704, the first modern synthetic pigment was created when the German Diesbach accidentally created Prussian blue. Other early synthetic pigments include chrome yellow (lead chromate, 1770s) and viridian (hydrated chromium oxide, 1838).
Organic pigments were also developed from coal tar, with synthetic ultramarine invented in 1828. By 1900, chemists had created hundreds of pigments, replacing traditional mineral and plant pigments with new stability. Important modern pigments like phthalocyanine and titanium white offered artists bold, vivid new colors.
The 20th century saw huge expansion in synthetic pigments. H.W. Sprenger created the first azo pigments in 1906, hugely expanding color possibilities. Today over 3,000 synthetic pigment varieties exist, though interest remains in rediscovering historic formulations.
History of Textile Dyeing
Like pigments, the earliest evidence of textile dyeing goes back to prehistory. Archaeologists have found evidence of dyed flax fibers from 36,000 BP Eastern Europe. Ancient Peru also has early examples of cotton textiles dyed with indigo, madder, and possibly cochineal.
Across ancient civilizations, natural dyes from plant, animal and mineral sources were commonly used to add color to fabrics and clothing. Plants like indigo, saffron, madder and woad provided blues, yellows, reds and greens for textile dyeing.
The 19th century saw synthesis of the first artificial dye color mauveine in 1856, sparking a dye revolution. By 1870, the developing synthetic dye industry supplied markets worldwide with affordable vivid clothing dyes, putting natural dyers out of business.
Today, over 10,000 unique synthetic dyes exist, supplying the demands of the clothing industry. Despite this diversity, natural dyeing retains an enduring appeal for its historic foundations and environmental sustainability.
Conclusion
Though prehistoric humans had access to natural pigments, the active manufacture of synthetic colors began across cultures worldwide around 5,000 years ago. Each civilization pioneered new techniques and materials, evidence of human creativity and innovation.
The 19th century chemical revolution drastically expanded the diversity and availability of pigments and dyes. The history of synthetic color is a story of science, trade, art and culture intertwining to create new tools for human expression. While synthetic pigments have environmental impacts, they continue to offer possibilities limited only by our imaginations.
