When the AI makes your photo look worse. Common mistakes that ruin colorization results and how to avoid them.
I ran an old family photo through an AI colorizer. The result was awful. My grandmother looked like she had orange skin and the background was an unnatural cyan blue. I almost gave up on AI colorization entirely.
Turns out the tool was not the problem. I was. AI photo colorization is not magic — it makes assumptions based on context, and if you feed it a photo with misleading visual cues, it guesses wrong. Here is what I did wrong and how to fix it.
I ran the colorizer on a photo that had not been restored first. Scratches and fading confused the AI. A scratch across my grandmothers face made the colorizer think it was a shadow. It applied a dark skin tone to what was actually a light-skinned person under a scratch. The result looked bruised.
The fix: restore first, colorize second. Use the photo restorer before the colorizer. Scratches, dust, and fading distort the grayscale information the AI uses to determine colors. A clean photo colorizes correctly. A damaged one colorizes unpredictably.
I knew my grandmothers dress was navy blue. I knew the couch was forest green. But I did not tell the AI any of this. It guessed the dress was brown and the couch was beige. It was not wrong — it was working with no hints.
Counter-intuitive: the colorizers optional text description field is not a suggestion. It is a command. If you know a color is right, tell the AI. The description field overrides the AIs context-based guessing. Write colors you are sure about and the AI fills in the rest around them. This is the single biggest quality improvement you can make.
I used Natural style on a photo that needed Vibrant. The result was muted and flat. Natural is designed for everyday photos in normal lighting. Vibrant is for photos where colors should pop — sunny outdoor scenes, colorful clothing, vivid landscapes. Portrait mode optimizes for skin tones. Classic emulates vintage hand-tinted photographs.
If the first result looks wrong, try a different style before changing anything else. The same photo with the same description can look dramatically different across styles. This is the fastest troubleshooting step.
The B and W colorizer costs 2 credits. Restore first, describe known colors, pick the right style. That is the difference between orange grandmother and natural skin tones.
