by michael daigle · 9 Jan 2024Have you ever wondered how paint came to be? You use it without thinking, applying a fresh coat to your walls or touching up the trim. But paint has a fascinating history spanning over 40,000 years. From cave paintings to modern acrylics, paint has evolved in remarkable ways.
Once upon a time, your options were limited to a few natural pigments and mediums. Ancient Egyptians used ochre and copper to add color, while the Greeks and Romans experimented with egg yolk and beeswax. As civilizations blossomed, new pigments were discovered through trade and exploration. But it wasn’t until the Industrial Revolution that paint became widely available.
Today, a trip to the hardware store reveals an overwhelming sea of color choices and sheens. We owe a debt of gratitude to the natural philosophers and craftsmen of yesterday who helped paint find its true colors. This is the story of that evolution.
The Origins of Paint in Prehistory
The earliest known paints date back to prehistoric times. Cave paintings found in Spain and France used pigments from the earth to create artistic renderings of animals and hunting scenes on cave walls. These natural pigments included red and yellow ochre, burnt sienna, and carbon from charcoal.
Around 3500 BCE, the Egyptians began using paints for decorative purposes. They created colorful paints using minerals like malachite, galena, and azurite. These were used in tombs and temples to create ornate decorations and hieroglyphics. The Egyptians also pioneered the first synthetic pigment, calcium carbonate, which they made from crushed limestone and egg whites.
The Romans further developed paint techniques, creating more vivid shades using mineral pigments, dyes, and organic materials. They used paint in murals, frescoes and portraits. New pigments introduced during this time included vermilion, verdigris, and lead white.
In the Middle Ages, new pigments emerged across Europe, including ultramarine, vermilion, and lead-tin yellow. Painters used egg yolk or linseed oil as binders, allowing them to achieve more luminous effects. The Renaissance saw an explosion of artistic creativity using these new pigments and techniques, as master painters created legendary works of art.
From prehistory to the Renaissance, each civilization built upon the knowledge of the past, discovering new pigments and developing innovative techniques that allowed for more creativity and artistic expression. The evolution of paint through these early periods set the foundation for all that would follow.
Early Paints in Ancient Egypt, Greece and Rome
The earliest known paints date back to ancient Egypt around 4000 years ago. The Egyptians used paints for decorating tombs, statues, and temple walls. Their paints were made from natural materials like lime, egg yolk, beeswax, and dyes from plants and minerals. These organic paints didn’t last long but showed how innovative the Egyptians were.
The ancient Greeks and Romans also used paints, often made of similar organic materials as the Egyptians. They painted buildings, portraits, murals and more. A red paint made of iron oxide pigment, called hematite, was popular and is still used today.
During the Middle Ages in Europe, paints were made from natural materials like berries, plants, and minerals. Egg tempera painting using egg yolk as a binder, was a common technique. Oil paints began to emerge, using linseed or walnut oil as a binder. This allowed artists to create paintings with more depth, richness and luminosity.
The Renaissance saw huge innovations in paints and painting techniques. New pigments were created, like ultramarine blue made from lapis lazuli. Advancements in oil paints and the emergence of canvas as a substrate enabled masterpiece paintings. Demand grew for more vibrant and chemically-stable pigments.
Synthetic pigments started being produced in the Industrial Revolution using chemical processes. Chrome yellow, viridian and cadmium red were introduced. Paints became more affordable and accessible to amateurs and professionals alike.
Today, we have a plethora of paint types - latex, alkyd, epoxy, urethane, and more. Advancements in pigments and binders have enabled paints that dry faster, last longer and come in any color you can imagine. Modern paints allow us to express creativity on any surface, interior or exterior. The evolution of paint has been a long and colorful journey.
The Middle Ages - Egg Tempera and Fresco Paints
The Middle Ages saw the rise of egg tempera and fresco paints in Europe. These paints used simple, natural ingredients to create decorative works of art in churches, palaces and homes.
Egg Tempera
Egg tempera was a popular choice for paintings during the Middle Ages. To make egg tempera, artists mixed egg yolks with pigments and water. The egg yolk acted as an emulsifier, binding the pigments to a wooden panel or canvas. Egg tempera produced a matte finish and allowed for precise details and crisp lines. Many famous works of the Middle Ages, like Botticelli's The Birth of Venus, were painted using egg tempera.
Fresco Painting
Fresco painting also became prominent in the Middle Ages. In fresco, artists applied water-based pigments to wet plaster on walls or ceilings. The pigments sank into the plaster as it dried, fusing the paint to the surface. Fresco painting allowed for large, dramatic works that decorated churches and public buildings. The dry climate of the Middle Ages was well-suited to fresco painting since the plaster needed to stay damp during application and the pigments required a dry environment to set properly. Famous fresco cycles of the Renaissance, like Michelangelo's masterpiece on the ceiling of the Sistine Chapel, were influenced by earlier medieval fresco painting.
While egg tempera and fresco painting limited the artist to a small color palette of mineral and earth pigments, these techniques produced enduring masterpieces that have stood the test of time. The paints of the Middle Ages were simple but effective, allowing skilled artists to create decorative and symbolic works of art that remain influential to this day.
The Renaissance - Development of Oil Paints
During the Renaissance, oil paints were developed and changed painting forever. These new paints revolutionized art, allowing for richer colors and more depth.
Oil paints were created by mixing dry pigments with drying oils, like linseed or walnut oil. The longer drying time of oils allowed artists to create smoother blends and more subtle gradations of color. This gave paintings a luminous, lifelike quality that couldn’t be achieved with egg tempera.
Jan van Eyck helped popularize oil painting in the early 15th century. His paintings featured vibrant colors, meticulous details, and an almost photographic realism. Other famous Renaissance oil painters include Leonardo da Vinci, Raphael, and Titian. Their masterful works demonstrate the visual richness that could be achieved with oils.
Over time, new pigments were discovered, expanding the color palette. Reds and blues were particularly prized, as they were more difficult to produce. The scarcity of certain colors meant that vivid shades were seen as luxurious and prestigious. Patrons eagerly sought paintings with the brightest, most expensive pigments.
While oil paints allowed for more naturalistic depictions, they were also more time-consuming. Multiple layers had to be built up and allowed to dry. This required patience but resulted in a luminous, three-dimensional quality. The slow drying time gave artists more flexibility to create subtle blends and glazes.
The introduction of oil paints was a pivotal moment that shaped the course of art. By giving artists a versatile, vibrant medium, oil paints enabled the rich visual expression that characterized the Renaissance. These paints dominated for centuries and still remain popular with artists today. Their development was a breakthrough that forever changed how we create and experience art.
The Industrial Revolution - Mass Production of Paint
The Industrial Revolution brought about several innovations that allowed paint to be produced on a massive scale. New machinery and manufacturing processes made paint more affordable and accessible to the general public.
The birth of synthetic pigments
Around 1800, chemists began creating synthetic pigments that produced bright colors. These man-made pigments were more vibrant and longer-lasting than natural pigments. Popular synthetic pigments included cobalt blue, chrome yellow, and emerald green.
Linseed oil and solvents
Linseed oil became the dominant medium for paints during this time. When mixed with pigments and solvents like turpentine, linseed oil produced a durable oil-based paint. Linseed oil paint was versatile and could be used on wood, metal, stone, and canvas.
Paint mills and mixers
Paint mills were introduced to grind pigments into fine powders to be mixed into linseed oil. Paint mixers blended the pigments, oils, and solvents together on a large scale. These machines allowed paint makers to produce paint in large volumes for sale to the public.
Ready-made paint
In the mid-1800s, ready-made paints were introduced, where the pigments and medium were already pre-mixed. People could now purchase cans of paint that just needed to be applied. Ready-made paints were more convenient and helped make DIY painting projects more popular.
Spray painting
The spray gun was invented in the late 1800s, allowing paint to be applied using compressed air. Spray painting resulted in an even coat and smooth finish. It was adopted first for industrial use but later became popular for residential painting.
Thanks to all these developments, by the end of the 19th century paint had become more affordable, accessible, and suitable for industrial and home use. The mass production of paint during the Industrial Revolution ultimately gave rise to the modern paint industry.
Paint Innovation in the 19th Century - Ready-Mixed and Metal-Based
In the 19th century, paint innovation exploded with the introduction of ready-mixed paints and new metal-based pigments.
Ready-Mixed Paints
Before the 1800s, you had to manually mix dry pigments with linseed oil to make paint. This was time-consuming and often resulted in uneven color and texture. In the 1830s, D.R. Averill & Co. introduced ready-mixed paints, pre-mixed to a uniform consistency. This made painting more accessible to DIYers and spurred a boom in the paint industry.
Zinc Oxide
Zinc oxide, a white powder, was first used as a paint pigment in the 1830s. When mixed into oil, it produced a durable white paint. Zinc oxide paint was used on everything from houses to bridges, helping make bright white the color of the era.
Chrome Yellow
Chrome yellow, one of the first synthetic pigments, was introduced in the 1820s. Made from lead chromate, it produced a vibrant lemon yellow color used by famous artists like Van Gogh. Chrome yellow paint was often used on walls, carriages, and signs.
Aluminum Paint
In 1865, aluminum bronze powder was introduced for use in metallic paint, producing a shiny silver-colored paint. Aluminum paint gained popularity for use on stoves, machinery, signs, and other applications where a metallic sheen was desired.
Other new pigments in the 19th century included vermilion, cobalt blue, and cadmium pigments. With the variety of new pigments, 19th-century artists and DIYers had a full rainbow of colors at their disposal for the first time. These innovative paints and pigments revolutionized decorative arts and spawned new painting techniques and styles. The world became a much more colorful place.
Modern Synthetic Paints - Latex, Epoxy, Polyurethane
Modern synthetic paints have revolutionized how we protect and decorate surfaces. Here’s a look at three of the most common and versatile options:
Latex Paint
Latex paint is a water-based paint that is popular for indoor use. It’s made of acrylic resins that form a durable, flexible coating. Latex paints are low odor, easy to clean up with water, and dry quickly. They provide good coverage in 2 coats and come in a wide range of sheens from flat to high gloss. Latex paint works well for walls, ceilings, and trim.
Epoxy Paint
Epoxy paint contains epoxy resins that produce an extremely hard, chemical-resistant finish. Epoxy paint must be mixed from a resin and hardener before using. It has a strong odor, so ventilation is important. Epoxy paint creates a thick coating that resists damage from chemicals, scratches, and stains. It’s commonly used for industrial floors, garage floors, and other surfaces that take a beating. Epoxy paint requires a primer and usually 2 coats for the best results.
Polyurethane
Polyurethane is a clear, protective finish that comes in a variety of sheens from satin to high gloss. It contains urethane polymers that create an durable, plastic coating. Polyurethane can be used over stained or painted wood to protect the surface while enhancing the appearance. It provides the best protection for wood floors, cabinets, furniture, and trim. Oil-based polyurethane has an strong odor and longer dry time but provides the most protection. Water-based polyurethane has little odor and dries quickly but may require more coats.
Modern paints and coatings offer convenience, durability, and an array of finishes tailored to your needs. With the right product and application, you can achieve professional-looking results and years of protection for any surface in your home.
The Digital Age - Computer Color Matching
The digital revolution has transformed nearly every industry, and paint and coatings are no exception. Advancements in computer technology have enabled innovations like color matching systems, allowing you to easily replicate a specific color.
Color Matching Software
In the 1970s, commercial color matching software and digital color matching systems were introduced. These systems use spectrophotometers to measure the color and spectral data of a sample. The software then determines the pigments and tints needed to recreate that color. This allows you to provide a paint retailer with a small sample of the color you want to match, and their system can generate the precise formula to duplicate it.
Accessible for Everyone
Today, many major paint brands offer in-store color matching using digital systems. This makes custom color matching accessible for both commercial and residential customers. Digital color matching has been a game changer, allowing you to replicate colors from photos, fabric swatches, or any sample. If you have your heart set on a particular shade, color matching ensures you can achieve that perfect color throughout your space.
Constant Innovation
Advancements in digital color technology continue at a rapid pace. Many paint companies now offer color matching apps and online tools to explore and share colors. New spectrophotometer designs provide faster, more accurate color readings. Artificial intelligence is improving color matching algorithms. All this progress allows for an ever-expanding color palette and the capability to match even the most obscure or complicated colors.
The digital revolution hasn’t just changed how we match and choose paint colors. It has also transformed how we research, buy, and even apply paint. But at its core, the goal remains the same: to provide you with the exact color you want. Digital color matching systems have made that goal more achievable than ever before.
The Future of Paint - Nanotechnology, Graphene, and Sustainability
The future of paint and coatings lies in nanotechnology, graphene, and sustainability. As technology advances, so do the materials and methods for applying paint.
Nanotechnology
Nanoparticles, measured in billionths of a meter, are enabling paints with exceptional durability, scratch resistance, and stain protection. Nanoparticles of clay and silica are already used in some paints to improve hardness and reduce gloss. Future nanopaints may be self-cleaning, anti-fouling, or change color. While promising, nanotech paints raise safety and environmental concerns to consider.
Graphene
Graphene, a super-strong form of carbon, could yield paints with extraordinary properties. Graphene-infused paints may conduct electricity, sense structural damage, or insulate better than current options. South Korean scientists have developed a graphene coating that prevents corrosion by protecting metals at the molecular level. Widespread use of graphene paint still faces cost and manufacturing challenges though.
Sustainability
The paint industry is improving sustainability through several avenues:
- Using renewable and recycled raw materials. Natural oils and recycled paint cans/containers are replacing petroleum-based ingredients and reducing waste.
- Creating zero- and low-VOC paints. Volatile organic compounds (VOCs) have been reduced up to 95% in some paints through alternative solvents and water-based formulations.
- Developing durable, long-lasting coatings. Longer time between repainting means fewer resources used and less pollution overall.
- Reclaiming and reusing paint. Some companies and organizations collect unused paint for resale or donation to communities in need.
The future of paint looks bright with innovations on the horizon to benefit both homeowners and the environment. While new technologies can bring risks, the paint industry is making progress toward sustainable, eco-friendly products that maintain or improve performance. The colorful history of paint continues to evolve.
