Humans have an unquenchable fascination with hue. The way a shade can lift our spirits, grab our gaze, or even define a nation’s identity is nothing short of magical. From ancient pigments that cost a king’s ransom to modern ribbons that rally entire continents, color has been an ever‑present player in the drama of human civilization. In this roundup we’ll explore 10 amazing ways colors have left an indelible mark on our world.

10 Amazing Ways Colors Have Influenced Our World

Back in the year 431, the Catholic hierarchy decided to assign specific colors to its most revered saints, granting the Virgin Mary a shade of blue that was then a rare and costly dye. This exclusive hue, which eventually evolved into the deep navy we recognize today, came to embody qualities like trust, purity, and innocence, and it even inspired the adoption of blue in police and military uniforms across the globe.

As centuries rolled on, the original sanctified aura of blue shifted toward notions of authority and, at times, even authoritarianism. Recognizing this evolution, the United Nations deliberately chose a lighter, sky‑blue for its peacekeeping forces, underscoring how a single color can travel from the altar to the arena of global diplomacy.

9 Color Tv Changed American Politics

When NBC first rolled out a fully color‑broadcast network in 1976, it introduced a luminous map that painted Republican‑leaning states in blue and Democratic‑leaning states in red. Other networks soon followed suit, yet by the 1980 election there was no uniform standard—some channels showed Reagan’s states in blue, others in red.

The turning point arrived during the nail‑biting 2000 presidential race, when networks finally settled on a consistent scheme: red for the Republican candidate George W. Bush and blue for the Democrat Al Gore. From that moment, the terms “red states” and “blue states” entered everyday political chatter and have remained fixtures of American discourse ever since.

8 Purple Proof Of Royalty

In the ancient Mediterranean, a humble sea snail called Bolinus brandaris secreted a mucus that could be turned into a vivid purple dye. Harvesting a single ounce required the crushing of roughly 250,000 of these snails, making the pigment astronomically expensive. A pound of this royal purple could buy a year’s wages for an average worker, cementing its status as the exclusive color of emperors, pharaohs, and high‑ranking officials across Rome, Egypt, and Persia.

The Byzantine Empire took the association to its zenith, draping its rulers in purple, signing edicts with purple ink, and even referring to heirs as “born in the purple.” The color remained a tightly guarded privilege in England until 1856, when a teenage chemist named William Henry Perkins inadvertently synthesized a synthetic purple while searching for an anti‑malaria remedy, finally democratizing the hue for everyday use.

7 Pink As A Color Of Support

The pink ribbon we now associate with breast‑cancer awareness actually sprang from a lineage of colored ribbons. In 1979, Penny Laingen used a yellow ribbon to show solidarity with her husband during the Iran hostage crisis. A decade later, Visual AIDS introduced a red ribbon to raise awareness for HIV/AIDS, prompting a wave of cause‑specific ribbons that culminated in The New York Times dubbing 1992 the “Year of the Ribbon.”

Eventually, pink emerged as the emblem for breast‑cancer advocacy, becoming perhaps the most successful ribbon campaign in history. From firefighters donning pink helmets to NFL teams sporting the hue on uniforms, the pink ribbon’s reach now spans continents, industries, and even construction equipment.

6 Orange Varnish Makes Music Worth Millions

Antonio Stradivari, the legendary luthier of the late 1600s and early 1700s, crafted violins whose sound continues to fetch tens of millions at auction. A striking feature of his instruments is the luminous orange varnish that coats each piece, a hue that has become synonymous with the very soul of a Stradivarius.

While it would be an oversimplification to credit the varnish alone for the unparalleled tone, researchers have long suspected that this orange coating contributed a vital element to the instrument’s resonance. Modern analysis reveals that Stradivari’s recipe relied on readily available materials, yet no contemporary maker has replicated the timeless brilliance of his orange‑finished masterpieces.

5 International Orange Defines A City

In the 1930s, most bridges were painted in utilitarian shades of black, gray, or silver. When engineers began constructing the massive suspension span over the Golden Gate Strait, architect Irving Morrow envisioned a color that would match the bridge’s grand scale and graceful form. He argued that the structure’s unprecedented size demanded an “unique and unconventional treatment from every point of view.”

Drawing inspiration from the red‑toned steel primer used during construction, Morrow assembled a multidisciplinary team of engineers, painters, and sculptors to experiment with pigments. Their collaborative effort produced a bold hue known as International Orange, a shade that would become inseparable from the bridge’s identity.

Today, International Orange not only defines one of the world’s most recognizable landmarks but also serves as a visual shorthand for the city of San Francisco itself, proving that a single color can become a city’s signature.

4 Yellow Topples A Tyrant

During Ferdinand Marcos’s authoritarian rule of the Philippines, opposition leader Benigno “Ninoy” Aquino favored the color yellow. After Ninoy’s assassination in 1983, mourners adopted the tune “Tie a Yellow Ribbon ’Round the Old Oak Tree” as a rallying cry, draping yellow ribbons around the airport where he fell.

Yellow quickly morphed into the emblem of the burgeoning People Power movement. Ninoy’s widow, Corazon Aquino, sported a bright yellow dress throughout her campaign, boldly declaring that the loss of her husband had stripped her of fear. The hue spread to every facet of the revolution—t‑shirts, banners, caps, even toilet paper—creating a sea of sunshine that symbolized hope and unity.

The massive, non‑violent three‑day rally attracted roughly two million participants, compelling the military and government to side with the protestors. Marcos ultimately fled, and Corazon Aquino was elected president in 1986, sealing the Yellow Revolution’s place in history.

3 White’s Role In Combat

In the Second Punic War, a Carthaginian vessel hoisted white wool and olive branches to signal a desire to surrender. The practice resurfaced in 69 CE during the Second Battle of Cremona, where a white banner again signaled a request for parley. Over time, the white flag became entrenched in Western tradition as the universal symbol of capitulation.

Simultaneously, ancient China during the Eastern Han Dynasty independently adopted white standards to denote non‑combatants, such as heralds, ensuring they were not mistaken for fighters. The white flag’s prominence grew so extensive that modern treaties now criminalize its misuse, treating deceptive deployment as a war crime.

2 A Morbid Brown Creates Cultural Heritage

Artists like Edward Burne‑Jones and Martin Drolling created masterpieces—such as “The Last Sleep of Arthur in Avalon” and “L’interieur d’une cuisine”—using a startlingly macabre pigment: ground‑up human mummies. By the 16th century, a thriving trade in mummified remains had emerged, supplying the market with “Mummy Brown,” a paint made from powdered human tissue.

While some contemporaries praised the pigment for its fluidity and delicate film, many found the practice repugnant. The controversy peaked when Burne‑Jones learned of the grisly origin of his brown tube; his widow recounted how he hurried to the studio, demanded the sole remaining tube be buried, and oversaw a solemn interment marked by a freshly planted daisy.

Despite its unsettling roots, Mummy Brown persisted in the artist’s palette well into the 20th century, with production continuing as late as 1964, illustrating how a color’s provenance can be as compelling as its visual impact.

1 A Green Poisoned Napoleon Bonaparte

The exact cause of Napoleon Bonaparte’s demise has sparked endless debate. While some point to a stomach ulcer, forensic examinations of his hair and the wallpaper in his Longwood exile home reveal a troubling presence of arsenic.

In the late 18th century, chemist Carl Scheele introduced a vibrant pigment called Scheele’s Green, which relied heavily on arsenic compounds. This toxic shade adorned the walls of Napoleon’s exile residence, exposing him to a potential source of the deadly element.

Subsequent analyses confirmed arsenic residues in both the wallpaper and Napoleon’s hair. Though it remains impossible to definitively declare the green pigment as the fatal agent, the evidence suggests that the very color that once brightened his surroundings may have contributed to his untimely end.

You may think you can splash any hue onto a canvas, a wall, or a piece of pottery whenever the mood strikes. Yet, the world of pigments hides a surprisingly shadowy roster of shades that are practically off‑limits. Whether they’re poisonous, tied up in ancient royalty, or locked behind exclusive licensing deals, these ten colors belong on a “do‑not‑use” list. Welcome to the top 10 forbidden colors you’ll never see in a mainstream paint store.

Why These Shades Are Top 10 Forbidden

10 Mummy Brown

In the sixteenth century, European artists suddenly started wielding a curious shade of brown that went by the macabre moniker “Mummy Brown.” Far from a fanciful label, the pigment was literally ground‑up ancient Egyptian mummies. The craze for all things Egyptian—so‑called “Egyptomania”—swept across Europe and the United States during the nineteenth century, turning mummies into décor, medicine, paper, and even party tricks at unrolling events. The exact recipes differed, but every version of the paint incorporated actual mummy tissue, making it virtually impossible for modern analysts to distinguish a work that employed the pigment without invasive testing.

The grim secret wasn’t always obvious. When the Pre‑Raphaelite painter Edward Burne‑Jones finally learned that his beloved brown hue was derived from ancient remains, he staged an impromptu funeral for the mummy in his own garden. The color’s reign, much like the civilization that birthed it, eventually ran out of steam. By 1964, the last known manufacturer announced they had exhausted their supply of mummified bodies, lamenting, “We might have a few odd limbs lying around somewhere but not enough to make any more paint.” Anyone hoping to recreate the shade today will quickly discover that sourcing the raw material is, to put it mildly, a dead end.

9 Vantablack

Vantablack is arguably the darkest substance ever engineered, gobbling up 99.965% of visible light. Developed by the British firm Surrey NanoSystems in the early 2000s, it earned a Guinness World Record for its light‑absorbing prowess until a less‑glamorous material called “dark chameleon dimers” snatched the title in 2015. Its applications range from coating telescope interiors to stealth technology for military camouflage, and even to experimental solar‑energy collectors. However, when it comes to artistic use, the paint is locked behind an exclusive licensing agreement.

The only artist legally permitted to employ Vantablack in a work of art is Anish Kapoor, whose fame stems from the iconic bean‑shaped Cloud Gate in Chicago. Kapoor’s monopoly sparked fierce backlash, prompting fellow creator Stuart Semple to launch an arsenal of alternative “for‑everyone” colors—Pinkest Pink, Black 2.0, Black 3.0, and Diamond Dust—explicitly barred from Kapoor’s hands. For those who still crave a near‑absolute black, Massachusetts‑based NanoLab offers a public‑available rival called Singularity Black, delivering a similarly abyssal effect without the licensing drama.

8 Tyrian Purple

Royalty has long been associated with a deep, reddish‑purple hue, and the ancient world took that connection to literal extremes. In the Roman Empire, any commoner daring enough to wear purple faced execution. Queen Elizabeth I codified the color’s exclusivity in her Sumptuary Laws, reserving it for the royal family alone. Known as Tyrian purple—or Imperial purple—the dye was so prized that it earned the nickname “the blood of the gods,” its hue reminiscent of dried blood and thus symbolizing divine lineage.

The rarity stemmed from a labor‑intensive extraction process. Phoenician workers in the city of Tyre harvested hundreds of thousands of sea snails, cracked their shells, and exposed the secret glands to sunlight, a method that emitted a horrendous odor. Roughly 250,000 snails were needed to produce a single ounce of dye, making the pigment as valuable as gold. The resulting color never faded, proudly displaying its owners’ wealth. The monopoly persisted until 1856, when teenage chemist William Henry Perkin, experimenting with anti‑malaria compounds, stumbled upon a cheap synthetic alternative—mauve—that finally democratized purple for the masses.

7 Vermillion

Vermillion, also called cinnabar or China red, shines with a vivid red‑orange that owes its brilliance to mercury. The finer the mercury particles, the brighter the hue. This pigment has a storied 8,000‑year history, from Roman artisans extracting it from Spanish mines for cosmetics and illuminated manuscripts, to medieval monks using it to embellish sacred texts. The mining process was perilous; prisoners and slaves toiled in the Spanish mines of Almadén, crushing the ore and heating it to produce the coveted pigment.

Chinese artisans also embraced vermillion, dubbing it “China red” and blending it with tree sap to adorn temples, pottery, and ink. Although the Chinese eventually synthesized cinnabar, the material remained toxic. By the twentieth century, cadmium red—far less hazardous and more stable—supplanted vermillion among artists. Nonetheless, the bold scarlet persists in Chinese culture as a symbol of luck and happiness.

6 Scheele’s Green

At the dawn of the nineteenth century, a dazzling shade of emerald green stormed Victorian high society. German chemist Carl Wilhelm Scheele unveiled the pigment, which quickly became the go‑to color for fashionable ladies attending soirées across Europe. The new gas‑lamp lighting of the era made night‑time gatherings brighter, and Scheele’s Green offered the perfect pop of vivid hue for dresses, wallpaper, carpeting, and even artificial foliage.

Unfortunately, the brilliance came at a deadly price. The pigment was concocted using copper arsenite, a compound riddled with arsenic. Wearers suffered blistering skin, families experienced green‑tinged vomiting, and factory workers faced organ failure. One tragic case involved a faux‑flower maker named Matilda Scheurer, who vomited green, turned the whites of her eyes green, and claimed everything she saw appeared green before she died. Despite early awareness of arsenic’s toxicity, the allure of the shade delayed public health warnings until 1895, when the fashion world finally abandoned the hazardous pigment.

10 Explanations For The Color Schemes Used On Everyday Things

5 Lead White

From as early as the fourth century B.C., ancient Greeks, Romans, and Egyptians relied on a thick, creamy white pigment known as lead white for everything from makeup to medicine to paint. Classical authors such as Pliny and Vestruvius documented its production, which involved soaking lead in vinegar and scraping off the resulting white powder. Artists who employed it often suffered from “Painter’s Colic,” a historic term now recognized as lead poisoning.

The pigment’s buttery consistency and rapid drying made it a favorite among European painters for centuries. However, lead exposure—whether inhaled, ingested, or absorbed through the skin—inflicts lasting damage on the brain and kidneys. Despite clear evidence of its toxicity, no suitable substitute matched its warm, creamy tones, so lead white persisted in studios until it was finally banned in the 1970s.

4 Uranium Orange

In 1936, the American ceramics giant Fiestaware introduced a bold orange‑red glaze dubbed “Fiesta Red.” The striking hue derived its color from uranium oxide, making the dishes literally radioactive. Production halted between 1943 and 1959 as uranium was diverted for wartime efforts, and when manufacturing resumed, the company switched to depleted uranium—a slightly less radioactive form.

Radioactive dinnerware was not unique to Fiestaware; many mid‑century ceramics incorporated uranium or other radioactive elements. The EPA now warns that such pieces can emit alpha, beta, and gamma radiation. Fiestaware continued producing the line until 1972, after which the collection became a coveted antique. Collectors still prize the original radioactive pieces, though experts advise against consuming food from them, especially acidic dishes. Modern Fiestaware still exists, but its colors now avoid uranium and lead entirely.

3 Radium Green

In 1908, a luminous green paint hit the market, glowing brightly in the dark and finding immediate use on watch and compass faces. Radium, the radioactive element responsible for the glow, flooded the consumer market at the turn of the century, appearing in drinks, candy, creams, soaps, spas, and even swimming pools. The glowing effect was marketed as a sign of health and vitality, and the military adopted radium‑lit watches during World War I.

The factories that applied the paint employed young women known as the “Radium Girls.” To achieve a fine brush tip, they licked their brushes, and many also dabbed the luminous paint onto their faces for a party‑ready glow. By the 1920s, workers began exhibiting severe radiation poisoning: jaw and tooth decay, painful sores, and eventual death. In 1928, Grace Fryer spearheaded a lawsuit against the New Jersey factory, drawing national attention and ultimately securing workers’ rights and safety standards. Radium paint fell out of use after 1968, replaced today by photoluminescent pigments that are safe and non‑radioactive.

2 Red‑Green and Blue‑Yellow

These paired hues aren’t outlawed by any ruler, nor are they made from hazardous substances. Instead, they’re practically invisible to the human eye because red and green, as well as blue and yellow, cancel each other out inside the retina. Our eyes translate incoming light into neural signals, and when these complementary colors stimulate the same photoreceptors simultaneously, the brain struggles to differentiate them, rendering the combination nearly indistinguishable.

In 1983, scientists Hewitt Crane and Thomas Piantanida conducted a clever experiment. Volunteers stared at adjacent red‑green or blue‑yellow stripes while an eye‑tracker forced each eye to focus on a single color. Over time, the eyes blended the hues, producing a new, indescribable shade. Participants struggled to name the color, as language lacked a term. A 2006 follow‑up by Dartmouth researchers led by Po‑Jang Hsieh gave volunteers a color‑mapper; many described the red‑green blend as a muddy brown, coining the term “mud.”

1 Gamboge Yellow

During the 1600s, the British East India Company imported a vivid yellow pigment from Southeast Asia, christening it “gamboge” after the historic name for Cambodia, Camoboja. The dye originated from the sap of mature trees, harvested after a decade of growth, then dried into powder or solid “rocks” that could be re‑wet for painting. While the sap itself was poisonous, gamboge also suffered from poor lightfastness, fading quickly and making it difficult for artists to preserve its brilliance over time.

In the mid‑1800s, a charlatan named James Morrison marketed “Morrison’s vegetable pills” made from gamboge, promoting them as a powerful diuretic and laxative. Physicians quickly recognized the sap’s irritant properties and its potential lethality in small doses. Decades later, a Winsor & Newton employee discovered a bullet embedded in a gamboge pigment sample, later traced to the Khmer Rouge’s killing fields, adding a grim historical layer to the color’s legacy. In 2005, Winsor & Newton retired the toxic version, replacing it with a safer synthetic alternative dubbed “New Gamboge.”
