You’ve seen them. Those eerie, overly-saturated historical photos where everyone looks like they’ve had a bad spray tan and the grass is a shade of neon green that doesn't exist in nature. It’s frustrating. We want to see our great-grandparents as they actually were—breathing, vibrant, and real—not as weird digital dolls. Honestly, trying to turn a black and white photo into color used to be a task reserved for high-end Photoshop wizards who spent forty hours clicking on individual pixels. Now? It’s a mess of AI apps, "one-click" promises, and a whole lot of historical guesswork.
The tech has moved fast. Maybe too fast.
When we look at a monochrome image, our brains fill in the gaps, but a computer has to guess. It has to decide if that gray coat was navy blue, charcoal, or maybe a dusty olive. If you get it wrong, the emotional connection breaks. It’s called the "uncanny valley" of colorization. To do this right, you need a mix of historical research, the right software, and a bit of artistic intuition.
Why Most People Fail at Adding Color
Most people just slap a filter on it. They find a free website, upload a 100-year-old family heirloom, and hope for the best. The result is usually "color bleed," where the blue of the sky leaks into the top of a building, or skin tones that look like flat peach paint.
Modern AI colorization—like what you see in DeOldify or the neural filters in Adobe Photoshop—uses something called Generative Adversarial Networks (GANs). Basically, two AI models argue with each other. One tries to color the photo, and the other tries to spot the fakes. Over millions of iterations, they get better. But they aren't perfect. They can't know that your grandfather's car was specifically "British Racing Green" unless you tell them. Without human intervention, the AI just plays it safe. It defaults to browns and grays because those are statistically "safer" bets for a computer.
Real experts don't just use one tool. They layer.
The Importance of Reference Materials
You can't just guess. If you’re colorizing a photo from the 1940s, you need to know what dyes were available then. Was that military uniform a specific shade of drab? Look it up. Historical accuracy matters because color carries meaning. If you color a 1920s flapper dress neon pink, you've turned a historical document into a cartoon.
I remember talking to a restorer who spent three days researching the specific shade of a mailbox in 1950s London just to get one background detail right. That’s the level of obsession required for high-quality work. You should check old catalogs, like Sears Roebuck archives, to see what colors people actually wore. It changes everything.

The Technical Reality of the Black and White Photo into Color Process
Let’s talk about bit depth. Most old scans are done in 8-bit, which is fine for looking at, but if you want to push colors around, you really want a 16-bit scan. This gives you more "room" in the files so the gradients don't break apart.
When you start to turn a black and white photo into color, the first step isn't color at all. It’s repair. You have to fix the scratches, the silvering, and the dust. If you try to colorize over a scratch, the AI will think that scratch is a physical object and try to give it a hue. It looks terrible.
- Scanning and Pre-processing: Use a flatbed scanner if you can. Phone apps are okay, but they add glare. Scan at 600 DPI. Minimum.
- Luminance Adjustments: Before adding red or blue, fix the contrast. Most old photos have faded. You need a true black and a true white point.
- Base Layering: This is where you use AI. Tools like Palette.fm or Photoshop’s Neural Filters provide a "suggestion." Think of this as your primer coat on a house.
- Manual Masking: This is the hard part. You create layers for skin, clothing, and background. You use "Color" or "Soft Light" blending modes in your editor.
- Color Variation: Human skin isn't one color. It’s a map of reds, yellows, and blues. There’s more blood flow in the cheeks and ears, so they should be warmer. The forehead is usually cooler. If you don't add these micro-tones, the person looks like a plastic mannequin.
Software That Actually Works in 2026
The landscape has shifted. We aren't just using brushes anymore.
Adobe Photoshop remains the industry standard because of its masking capabilities. The "Colorize" filter is a great starting point, but the real magic happens when you use the "Curves" tool to manually adjust the CMYK channels. It’s tactile. You feel like you’re developing the photo in a darkroom.
DeOldify is the open-source hero. Created by Jason Antic, it’s arguably the most sophisticated AI model for this. It handles "liminal" spaces—like the transition between hair and a hat—better than almost anything else. If you aren't a coder, you can find versions of it hosted on sites like MyHeritage, though they often add a watermark.
CapCut and Mobile Apps: Look, they're fine for a quick Instagram story. But they're aggressive. They smooth out skin textures until the person looks like they’ve been blurred into oblivion. If you care about the soul of the photo, avoid anything that promises "HD Face Enhancement" along with the color. It replaces your relative's actual face with a generic AI-generated face that looks "similar." It’s creepy.
The Problem with "AI Sharpening"
There’s a massive trend of upscaling photos while colorizing them. Tools like Topaz Photo AI are incredible, but they can be deceptive. They "hallucinate" detail. If a photo is blurry, the AI might add eyelashes that weren't there or change the shape of an eye. When you're trying to turn a black and white photo into color, you have to ask yourself: Do I want a perfect image, or do I want a truthful one?

I usually tell people to keep the grain. Film grain is beautiful. It’s the texture of history. When you remove it, the color looks like it's floating on top of the image rather than being part of it.
Case Study: The 1930s Street Scene
Imagine a photo of a rainy street in New York, 1934. If you just hit "auto-color," the AI will probably make the wet pavement gray and the yellow cabs a dull mustard.
A pro will look at that and realize the wet pavement should reflect the colors of the neon signs above. They’ll add a hint of cobalt blue to the puddles. They’ll look up what color the New York taxis were that year (it wasn't always the "School Bus Yellow" we know today). They’ll add "atmospheric haze"—that slightly blue-ish tint that happens when objects are far away.
This is called "color perspective." It’s what separates a hobbyist from an expert.
Step-by-Step Guide to a Realistic Result
If you're doing this at home, don't rush.
First, get a clean scan. If the photo is stuck behind glass, don't rip it out. Take it to a professional. Once you have your digital file, open it in your editor and convert it to RGB mode. Even though it looks gray, it needs those three color channels to hold the new data.
Next, create a "Curves" adjustment layer. Bump the contrast slightly. Now, bring in your AI colorizer of choice to get the base.

The real secret? The HSL Slider. (Hue, Saturation, Lightness).
Most AI colorization is too saturated. Turn the saturation down by about 10-15%. Old photos shouldn't look like they were taken on an iPhone 16. They should have a slightly muted, organic feel.
Focus on the eyes. The "white" of a human eye is almost never pure white. It’s slightly cream or even a tiny bit blue-gray. If you leave it pure white from the original B&W photo, the person will look like they’re staring into your soul in a very uncomfortable way.
Why We Are Obsessed With This
There is something biological about it. Our ancestors didn't live in a gray world. They saw the same blue sky and the same red roses we do. When we turn a black and white photo into color, we are removing a barrier. We are admitting that they were just as "in color" as we are.
It makes history feel less like a textbook and more like a memory.
But there’s a flip side. Some historians argue that colorizing photos is a form of vandalism. They believe the photographer’s choice to use black and white was an artistic one. While that’s true for Ansel Adams, it’s rarely true for your Great Aunt's birthday snapshot from 1952. She used B&W because color film was expensive and hard to process. In those cases, colorization is an act of restoration, not an insult to the artist.
Common Pitfalls to Watch Out For
- The "Glowing" Effect: This happens when you don't align your color layers perfectly. You see a halo of color around someone's head. Zoom in to 300% and clean those edges with a soft brush.
- Uniformity: Nothing in nature is one solid color. A brick wall has reds, oranges, purples, and grays. If you fill it with one "brick" color, it looks like a video game from 1995.
- Ignoring the Lighting: If the sun is coming from the left, the colors on the left side of the face should be warmer (more yellow/orange) and the shadows on the right should be cooler (more blue/purple).
Actionable Insights for Your First Project
If you're ready to try this, start with a photo that has a clear subject and a simple background.
- Download GIMP or use Photopea if you don't want to pay for Photoshop. They both support layers and blending modes.
- Use Palette.fm for your initial AI color pass. It offers several different "palettes" (like "Outdoor Vibrant" or "Heritage") that give you a better starting point than a generic one-size-fits-all tool.
- Research the era. Spend ten minutes on Google Images looking at "1940s color photography" or "Kodachrome slides" to get a feel for the color palette of the time.
- Focus on the skin. If the skin looks right, the viewer will forgive almost anything else. Use at least three different shades for the face: a base tone, a pinker tone for the cheeks/nose, and a slightly yellower tone for the forehead.
- Keep the original. Always work on a duplicate layer. You want to be able to toggle the color on and off to make sure you haven't lost the "spirit" of the original photo.
Colorizing is a bridge between then and now. It’s a way to sit down at the table with people who are long gone. Just remember to keep it subtle. The goal isn't to make it look like a modern photo; the goal is to make it look like a window into the past that finally has the lights turned on.
