Short answer: no. The most repeated story about Thomas Gainsborough's The Blue Boy, that he built an entire portrait out of blue satin just to embarrass his rival Sir Joshua Reynolds, cannot be true. Reynolds didn't put his warm-versus-cool color rule into words until 1778. Gainsborough had already finished the painting, and shown it publicly, eight years earlier.
That one date gap collapses the whole legend. But the real history behind The Blue Boy, who actually invented the rivalry story, who the boy might really be, and how the painting ended up 5,000 miles from where it was painted, is stranger than the myth it replaced.
The story you've probably heard
If you know one thing about The Blue Boy, it's probably some version of this: Sir Joshua Reynolds, first president of the Royal Academy, lectured his students that a painting's brightest passages had to be warm colors, yellows, reds, a warmish white. Blue, gray, and green belonged in the shadows, never at center stage. Gainsborough took it as a challenge, so the story goes, and painted a life-size boy in gleaming blue silk, planted him dead center, and dared anyone to say it didn't work.
Two rival painters. A public dare. A masterpiece born out of spite. Great story. As far as anyone has ever been able to prove, it's invented.
What Reynolds actually said, and when he said it
Reynolds delivered his color rule in his Eighth Discourse, a lecture given to Royal Academy students on December 10, 1778, at the annual prize ceremony. His actual words were narrower than the legend suggests. The masses of light in a picture, he said, should always be a warm, mellow color (yellow, red, or yellowish white). Blue, gray, or green should stay almost entirely out of those lit passages, used only to support or set off the warm ones.
That's a rule about where the light falls, and nothing more. Reynolds never said a picture couldn't be blue. He only said the brightest, most eye-catching passage should stay warm. That's still decent color theory: warm tones read as advancing, cool tones as receding, so a painter's eye (and honestly, anyone hanging a wall of prints) tends to put warmth where it wants your attention to land first.
The dates that don't add up
Gainsborough's portrait, originally titled A Portrait of a Young Gentleman, was finished and hanging at the Royal Academy's annual exhibition in 1770. It didn't pick up the nickname "The Blue Boy" until roughly 1798, ten years after Gainsborough had died. Line up the dates and the rivalry story falls apart on its own terms.
| The claim | The documented history |
|---|---|
| Gainsborough painted The Blue Boy as a rebuttal to Reynolds' warm/cool color rule | The painting was finished and exhibited in 1770; Reynolds didn't state that rule until 1778, eight years later |
| The rivalry comes from something the painters themselves said or wrote | Neither man is recorded ever mentioning it in a letter, diary, or interview |
| It's a minor mix-up; the story is still roughly true | The rebuttal story wasn't published until 1821, fifty-one years after the painting, by a man who never knew either of them |
You can't rebut a lecture that hasn't been given yet.
The man who published the "proof," fifty years later
So where did the story come from? A printmaker named John Young.
In 1821, Young, who worked as keeper of the British Institution, published the first widely circulated engraving of the painting. Engravings sold better with a hook, and Young supplied one: he wrote that Gainsborough had painted the boy specifically to prove Reynolds wrong.
By then, Reynolds had been dead for thirty-three years and couldn't correct the record. Gainsborough had been dead just as long. Nobody who'd actually known either man was left to say "that's not what happened." Young's version answered a real question, why an anonymous boy in fancy dress had become the most famous painting in Britain, and it was a far better answer than "we don't really know." The invented rivalry did what it was built to do. It sold engravings, and the painting's fame took off right along with them. The story has outlived every correction since.
Nobody agrees on who the boy is, or why he's dressed like it's 1630
The sitter has traditionally been named as Jonathan Buttall, a wealthy hardware merchant's son and a family friend of Gainsborough's. Even that's disputed. In 2013, art historian Susan Sloman argued the model was more likely Gainsborough Dupont, the painter's own nephew and studio assistant, who sat for several of his uncle's works around the same years. No contract, letter, or receipt has ever surfaced to settle it either way.
What's not in dispute is the costume, and it's stranger than it looks. The satin doublet, the lace collar, the slashed sleeves: none of that was 1770s fashion. It's a close copy of the court dress Anthony van Dyck painted a century and a half earlier, in the 1630s.
What's notable is that Gainsborough usually avoided this kind of costume. He was known for preferring his sitters in their own current, fashionable clothes, arguing it made for a truer likeness. It was Reynolds, of all people, who favored dressing subjects in historical grand-manner costume. For Gainsborough to reach for antique Van Dyck dress here was the exception, not the habit.
Set the myth aside and look at the actual canvas, and Gainsborough didn't disprove Reynolds so much as prove his point. The lightest, warmest passage isn't the suit. It's the boy's face and the pale lace at his throat, glowing against the blue instead of competing with it, doing exactly what Reynolds said a warm passage should do.
The rivalry was real. So was the reconciliation.
None of this means Gainsborough and Reynolds got along. They were the two most successful portrait painters in Georgian London, competing for the same wealthy sitters for over two decades. By most accounts they stayed cool toward each other for most of their careers. Reynolds favored the Royal Academy's formal, academic art of the grand manner. Gainsborough painted faster, looser, and cared more about a likeness than a lecture.
The real ending is better than the invented rivalry. In 1788, dying of cancer, Gainsborough sent word asking Reynolds to visit him. Reynolds came. Later that year he served as one of the pallbearers at Gainsborough's funeral, and that December he devoted his Fourteenth Discourse, the same lecture series that supposedly started this whole feud, to a tribute to Gainsborough's technique: the "odd scratches and marks" that looked like chaos up close and resolved into something true to nature from a few steps back.
The painting outlived both men by more than a century before its own history got interesting again. Buttall, or whoever the sitter really was, kept it until an 1796 bankruptcy forced a sale. It passed through a couple of private owners, including, fittingly, a rival portrait painter named John Hoppner, before the Grosvenor family, later the Dukes of Westminster, held it for over a hundred years.
In 1921, the second Duke of Westminster sold it through the dealer Joseph Duveen, whose entire business ran on one observation: Europe had the art, and America had the money. The buyer was railroad magnate Henry E. Huntington, and the price, $728,800, made it the most expensive painting ever sold at the time. Before it shipped to California, the National Gallery in London gave it a three-week farewell exhibition. Ninety thousand people came to see it off. Street vendors sold cheap copies outside. Some Londoners protested the sale outright.
It's been in Huntington's collection in San Marino ever since, on loan just once. In January 2022, it went back to London's National Gallery for a special exhibition alongside the Van Dyck paintings that inspired its costume, opening on the hundredth anniversary, to the day, of the afternoon it left.
Frequently Asked Questions
What size is The Blue Boy?
It's a full-length example of British figurative art, in oil on canvas, 177.8 by 112.1 centimeters (about 70 by 44 inches), close to life-size for the boy shown.
Did conservators find anything when they examined the canvas?
A public conservation project at the Huntington ran from 2013 through 2019, X-raying and scanning the painting in view of visitors. It turned up an 11-inch tear in the lower left corner, expertly repaired sometime in the early 1800s, most likely from rough handling during a move.
Was dressing portrait sitters in Van Dyck-style costume common at the time?
Yes. It was a recognized trend among wealthy Georgian patrons, sometimes called Van Dyck dress, and a handful of the actual satin-and-lace costumes survive in collections today. Gainsborough painted other sitters in similar attire; The Blue Boy just happened to be the one that became famous.
Who was Joseph Duveen, the dealer who brokered the sale?
Joseph Duveen was the dominant art dealer of the early twentieth century, known for buying old masters from cash-poor European aristocrats and selling them to American industrialists. His clients also included Henry Clay Frick and Andrew Mellon, whose purchases through Duveen went on to form the core of the Frick Collection and the National Gallery of Art in Washington.
Did Reynolds and Gainsborough ever cross paths beyond this rumor?
Constantly. Both were founding members of the Royal Academy in 1768, with Reynolds serving as its first president, and both exhibited in the same annual shows at Somerset House for two decades. That proximity is what made a rivalry so easy for a printmaker to invent fifty years later, and so easy for readers to believe ever since.
