A Brief History of Photo Colorization: From Hand-Painted to AI

There is something about a black-and-white photograph that feels like it belongs to a different world. The faces stare back at us across the decades, but they feel distant. Remote. Almost fictional.

Adding color changes everything. Suddenly, the woman in that old portrait has rosy cheeks and brown eyes. The soldier has a blue uniform and sunburned skin. The past stops being an abstraction and becomes real.

But how did we get from painstakingly painting watercolors onto daguerreotypes to AI that can colorize a photo in seconds? The answer stretches back nearly two centuries, and if you are old enough to remember Ted Turner making headlines for colorizing Casablanca, you have lived through some of the most dramatic chapters yourself.

The Earliest Days: Painting Color by Hand (1839-1900s)

Photo colorization is almost as old as photography itself. When Louis Daguerre introduced the daguerreotype in 1839, people were fascinated but also a bit disappointed. They were accustomed to colorful paintings. These silvery, monochrome images felt incomplete.

Within months, artists started fixing that problem. Swiss painter Johann Baptist Isenring is credited with the first hand-colored daguerreotypes, using a mixture of gum arabic and pigments applied to the delicate surface and fixed with heat. By 1842, variations of his technique had been patented in both England and France.

A New Profession Is Born

Hand-coloring quickly became its own industry. Portrait painters, whose livelihoods were threatened by photography, adapted by offering their skills to photographers. As early as 1849, the photography journal editor Samuel D. Humphrey wrote that coloring "created more popular clamor than all the other inventions combined."

The work was painstaking. Artists used fine brushes, cotton swabs, and even their fingertips to apply watercolors, oils, and pastels directly to prints. Cheeks were tinted pink. Lips were reddened. Gold highlights were dabbed onto jewelry and military buttons.

The Japanese Masters

While hand-coloring was invented in Europe, it reached its artistic peak in Japan. Beginning in the 1860s, photographer Felice Beato and his partner Charles Wirgman brought the technique to Japan, where it merged with the country's refined traditions of watercolor painting and woodblock printing. Japanese hand-colored photographs from this era remain some of the most beautiful examples ever produced.

Why It Mattered

Hand-coloring did more than make photos prettier. It democratized something that had once been reserved for the wealthy. Before photography, only the rich could afford painted portraits. Now, middle-class and working-class families could have "painted" portraits of themselves and their loved ones, often for the first time in their family's history.

If you have old family photos from the late 1800s or early 1900s with soft, painted-looking color, those were done by hand. Every single one.

The Kodachrome Revolution and the Decline of Hand-Coloring

Hand-coloring persisted well into the 20th century, but its days were numbered. In 1907, the Lumiere brothers introduced the autochrome, the first commercially successful color photography process. Then in 1936, Kodak released Kodachrome, and everything changed.

Kodachrome made color photography practical and affordable. By the 1950s and 1960s, most family snapshots were being taken in color. Hand-coloring faded from mainstream use, surviving mainly as an artistic niche.

But the story of colorization was far from over.

The Ted Turner Controversy: Hollywood's Great Colorization War (1980s)

If you were watching television in the late 1980s, you almost certainly remember the uproar. Ted Turner had purchased the entire MGM film library in 1986, acquiring rights to over 3,650 classic films. Then he announced his plan: he was going to colorize them.

Turner's logic was straightforward and purely commercial. By the mid-1980s, nearly every American household had a color television. Black-and-white films did not sell ads or move VHS tapes the way color films did. The numbers backed him up. One distributor had sold 46,000 copies of a Shirley Temple compilation in black and white. The colorized version moved 1.2 million copies.

"The Barbarians Are at the Gate"

Hollywood erupted. For a time, film colorization was the most controversial topic in the entertainment industry.

Jimmy Stewart called it a "terrible injustice." He tried to watch the colorized version of It's a Wonderful Life but had to turn it off because it made him feel sick. He testified before Congress, describing the process as dunking a film in "a bath of Easter Egg dye." He pointed out one particularly tone-deaf choice: someone had dressed the character Violet in all-violet costumes, "the kind of obvious visual pun that Frank Capra never would have considered."

George Lucas told Congress that "those who deface our cultural heritage are barbarians." Orson Welles, before his death in 1985, told associates to prevent Turner from "coloring my movie with his crayons." Siskel and Ebert devoted a special 1986 episode to what they called "Hollywood's New Vandalism."

Turner's Defiant Response

Turner was utterly unapologetic. "I did it because I wanted to do it, and it's mine," he said. He compared colorization to the common practice of television stations editing films to fit time slots. The films were his property, he argued, and he could do what he liked with them.

The Breaking Point: Casablanca and Citizen Kane

The controversy reached its peak in 1988 when Turner released a colorized Casablanca. Critics were appalled. Then Turner set his sights on Citizen Kane, but this time he was stopped. Orson Welles' original contract with RKO granted him absolute artistic control and specified the film would be in black and white. It was one of the few times legal protections halted the process.

The Lasting Impact

The backlash led to the National Film Preservation Act of 1988, which created the National Film Registry and required proper labeling of colorized films. In France, Anjelica Huston won a 1991 court case that prevents the distribution of colorized films against the wishes of the original creators.

And then something unexpected happened. Turner largely stopped colorizing films because of the high cost, and in 1994 he launched Turner Classic Movies, a channel dedicated to showing the MGM library in its original black-and-white glory. The man who had been called a cultural vandal ended up becoming one of classic cinema's greatest preservers.

The Digital Era: Photoshop and Professional Colorization (1990s-2000s)

While Hollywood was fighting over films, digital technology was quietly transforming photo colorization. Adobe Photoshop, released in 1990, gave skilled artists powerful new tools to add color to black-and-white images.

Digital colorization was a massive improvement over hand-painting. Artists could work in layers, undo mistakes, adjust hues with precision, and zoom in to the pixel level. But it was still labor-intensive. A single photo could take a skilled artist anywhere from several hours to several days, depending on its complexity.

The Research-Driven Approach

Professional colorizers like Jordan Lloyd and Sanna Dullaway elevated the craft into a form of visual scholarship. They would dig into military records, newspaper accounts, diaries, and historical archives to determine accurate colors. A Civil War soldier's enlistment records might include descriptions of hair color, eye color, and uniform details. Lloyd explained that "seeing something from that long ago in color helps us understand it a little better because color plays a major part in how we interact with the world."

In 2015, TIME magazine commissioned Dullaway to colorize 30 of the 100 most influential photographs of all time. The results were striking, demonstrating how color could make iconic moments feel immediate and real.

The AI Revolution: Deep Learning Changes Everything (2016-Present)

The year 2016 was a turning point. Researchers at UC Berkeley, led by Richard Zhang, published a paper called Colorful Image Colorization that changed the field overnight. Instead of treating colorization as a painting problem, they treated it as a classification problem, training a convolutional neural network on over a million color images to predict what colors should appear in a grayscale photo.

The same year, researchers Satoshi Iizuka, Edgar Simo-Serra, and Hiroshi Ishikawa published Let There Be Color!, which used deep learning to understand both local details and the overall scene when applying color.

From Lab to Living Room

The breakthrough moved quickly from academic papers to consumer tools. In 2018, software engineer Jason Antic released DeOldify, an open-source colorization tool based on generative adversarial networks. In February 2020, MyHeritage launched its In Color feature, powered by DeOldify's technology, and it went viral. More than 20 million photos were colorized through the platform.

Adobe added Neural Filters to Photoshop, allowing one-click colorization. Services like PhotoRevive emerged, using the latest AI models to deliver high-quality colorization that would have been unimaginable just a decade ago.

How AI Colorization Actually Works

Modern AI colorization analyzes the shapes, textures, and context in a black-and-white photo. It recognizes that sky tends to be blue, grass tends to be green, and skin tones fall within certain ranges. It draws on patterns learned from millions of images.

The results are not perfect and never will be in an absolute sense. AI cannot know that your grandmother's favorite dress was yellow or that your grandfather's eyes were hazel. But the technology produces remarkably plausible results and continues to improve with each new generation of models.

Famous Colorized Photos and Their Impact

Some of the most powerful colorized images have reshaped how we connect with history.

Dorothea Lange's Migrant Mother from 1936, one of the most famous photographs of the Great Depression, takes on a completely different emotional weight when you can see the worry lines and weathered skin in natural tones. The March on Washington in 1963, where Martin Luther King Jr. delivered his "I Have a Dream" speech, becomes more vivid and immediate when you can see the diversity of the crowd in color.

These colorizations are not replacements for the originals. They are interpretations, a bridge between the past and the present. And for many people, especially those whose family photos exist only in black and white, that bridge is deeply personal.

Where Is Colorization Heading?

The technology is advancing rapidly. Today's AI models produce results that would have amazed the hand-colorists of the 1800s and horrified Ted Turner's critics of the 1980s in equal measure.

We are moving toward AI that can handle not just photos but video, colorizing entire films frame by frame with consistent, realistic color. Interactive tools let users guide the AI, specifying that a dress should be red or a car should be forest green. Resolution enhancement and colorization are merging, allowing old, faded photos to be both sharpened and brought to life in color simultaneously.

A Thread That Runs Through Time

From Johann Baptist Isenring carefully dabbing pigments onto a daguerreotype in 1839 to a neural network analyzing millions of images in 2026, the impulse behind photo colorization has never changed. We want to see the past as it really looked. We want to feel connected to the people who came before us.

If you have old family photos sitting in a shoebox or an album, know this: the technology to bring them to life has never been better, easier, or more affordable than it is right now. The hand-colorists of the 19th century would be astonished. Jimmy Stewart might even approve.
