The Feud Over the World's Darkest Color That Accidentally Advanced Science
The Black That Started a War
In the art world, few things are more precious than a new color. So when British artist Anish Kapoor secured exclusive artistic rights to Vantablack — a substance so dark it absorbs 99.965% of visible light — he didn't just gain access to a revolutionary pigment. He accidentally triggered the most bizarre scientific feud of the 21st century.
Vantablack wasn't supposed to be an art supply. Created by Surrey NanoSystems in 2014, this forest of carbon nanotubes was designed for military and space applications. When light hits its surface, it gets trapped and bounced around until it's completely absorbed, creating the visual effect of staring into a void. Objects coated in Vantablack lose all sense of dimension and depth, appearing as flat black silhouettes that seem to have been cut out of reality itself.
The substance was so revolutionary that Surrey NanoSystems could barely keep up with requests from aerospace engineers, satellite manufacturers, and defense contractors. Then Anish Kapoor came calling.
The Monopoly That Broke the Art World
Kapoor, famous for massive sculptures like Chicago's "Cloud Gate" (the giant reflective bean), saw Vantablack's artistic potential immediately. In 2016, he negotiated exclusive rights to use the pigment in art, meaning no other artist on Earth could legally purchase or work with the darkest substance ever created.
The art community exploded in outrage. Painters, sculptors, and installation artists who had dreamed of working with Vantablack found themselves locked out by what many saw as an unprecedented act of artistic greed. Social media erupted with accusations that Kapoor had "stolen" a color from humanity.
But one artist decided to fight back in the most creative way possible.
The Pink That Hurt to Look At
Stuart Semple, a British painter and materials scientist, was furious about Kapoor's monopoly. But instead of filing lawsuits or organizing protests, Semple headed into his laboratory and began experimenting with fluorescent pigments. His goal was ambitious and slightly insane: create the brightest pink ever made and release it free to every artist in the world — except Anish Kapoor.
After months of chemical experimentation, Semple emerged with something unprecedented: Pink, a fluorescent pigment so intensely bright it was literally painful to look at directly. The color was so saturated it seemed to glow with its own light, creating an almost three-dimensional effect that made viewers' eyes water.
Semple put Pink up for sale online for just £3.99, with one crucial restriction: buyers had to confirm they were not Anish Kapoor and would never share the pigment with him. The product description read like a legal document crossed with a playground taunt.
The Color War Escalates
Kapoor's response was perfect in its pettiness. He obtained some Pink (reportedly through an intermediary), dipped his middle finger in it, and posted a photo on Instagram with the caption "Up yours #pink." The art world had officially descended into the most sophisticated finger-painting fight in history.
Semple wasn't finished. Over the next several years, he developed an entire arsenal of exclusive pigments, each more extreme than the last. There was Black 2.0, a paint so dark it rivaled Vantablack but remained available to all artists. Then came Black 3.0, even darker than its predecessor. He created the world's most reflective silver, a blue so pure it seemed to emit its own light, and a green so vibrant it appeared to move.
Each release came with the same restriction: available to everyone except Anish Kapoor.
The Accidental Scientific Revolution
What started as an artistic feud had accidentally become a materials science revolution. Semple's quest for increasingly extreme pigments pushed him to develop new chemical processes and nanotechnology applications that had never been attempted for artistic purposes.
His Black 3.0, for example, uses a completely different approach than Vantablack's carbon nanotubes. Instead of trapping light in microscopic tubes, it employs specially engineered particles that scatter and absorb light through multiple mechanisms simultaneously. The result is a paint that's nearly as dark as Vantablack but can be applied with a regular brush.
Meanwhile, his fluorescent pigments achieved their intensity through quantum dot technology typically used in high-end television displays. Semple had essentially miniaturized cutting-edge screen technology into paint form.
The Unexpected Consequences
The feud attracted attention from researchers around the world who realized that the competition between Semple and Kapoor was driving innovations in light absorption and reflection that could have applications far beyond art. Military researchers became interested in Semple's ultra-matte blacks for stealth technology. Display manufacturers wanted to license his fluorescent formulations. Even NASA expressed curiosity about his light-absorbing materials for space applications.
What had begun as a petty dispute over artistic access had accidentally accelerated materials science research by years, possibly decades. The art world's most ridiculous feud was generating patents, academic papers, and commercial applications that neither artist had anticipated.
The Battle That Never Ends
Today, the Kapoor-Semple feud continues to simmer. Kapoor still maintains exclusive rights to Vantablack (though Surrey NanoSystems has since developed Vantablack 2.0 and other variants with different licensing terms). Semple continues to develop new pigments, each release accompanied by increasingly elaborate restrictions against Kapoor.
The latest development came in 2019 when Semple created "Diamond Dust," a pigment made from actual crushed diamonds that creates a sparkling effect impossible to achieve through any other means. True to form, it's available to everyone except one very specific British sculptor.
The Absurd Legacy of a Color War
The Vantablack feud represents something uniquely modern: a dispute so petty it accidentally advanced human knowledge. Two artists' inability to share their toys pushed materials science into territories that pure research might not have explored for years.
In laboratories around the world, researchers now study "Semple-type" fluorescent compounds and "Kapoor-exclusion" light absorption techniques. Academic papers cite the "artistic pigment wars" as inspiration for new approaches to manipulating light and color.
Perhaps most remarkably, both artists seem to have benefited from their eternal conflict. Kapoor's Vantablack sculptures draw massive crowds fascinated by surfaces that seem to defy physics. Semple has built a global community of artists united by their shared exclusion from one very expensive black paint.
The feud over the world's darkest color may have started with artistic ego, but it ended up proving that sometimes the most important discoveries come from the most ridiculous places. In the annals of scientific advancement, few stories are stranger than the tale of two artists who couldn't share their crayons — and accidentally changed materials science forever.
