How do you colorize a photo with AI?

To colorize a photo with AI, upload the black and white photo and ask for natural colours, keeping every face the same; the model can also repair scratches and fading in the same step. On Kenerate AI, Seedream 5.0 Pro gave the most natural results on four old photos. It suits family historians and anyone reviving old prints.

Tips

Get natural colours

What worked in our tests.

  • Scan or photograph the print flat, in even light, without glare.

  • Say “natural colours” and “keep every face the same”.

  • If you know real colours (a blue dress, a red car), name them.

  • Ask for repairs in the same step: scratches, creases, fading.

  • For very small prints, upscale first.

  • Colours are an educated guess — label colorized family photos as such.

FAQ

Colorize Photo with AI questions

How do I colorize a black and white photo?

Upload a flat, glare-free scan to Seedream 5.0 Pro in /app/image and ask for natural colours while keeping every face the same. Name any colours you know — a blue dress, a red car — for more accurate results, and ask for repairs to scratches, creases and fading in the same prompt. Upscale the result if you plan to print it.

Link to this answer

Is it free?

Yes, to start. A new Kenerate account gets free starter credits on sign-up, and Flux 2 Dev is on the free plan. Seedream 5.0 Pro, which gave the most natural results on our four test photos, needs a one-time credit pack rather than a subscription, and credits never expire. It works online in your browser, and downloads have no watermark.

Are the colours accurate?

Not exactly. They are a realistic guess: the model has learned the colours objects usually have, such as skin, sky, grass and fabrics, and repaints the grayscale image with plausible tones. If you know the real colours, put them in the prompt. For family history, keep the original scan and label the colour version as an interpretation.

Can it fix scratches too?

Yes. Ask for colour and repairs in one prompt, as in the examples on this page — for example “restore and colorize this snapshot: fix the crease and fading, natural summer colours”. Seedream 5.0 Pro fixed scratches, creases and paper ageing on our test photos while keeping faces and poses the same. For very small prints, upscale first.

Can I colorize a sepia photo?

Yes. Sepia prints colorize the same way as black and white ones: ask for natural colours and to remove the paper ageing, and keep the face the same. The 1930s portrait on this page started as a sepia print and came back with natural skin tones, a dark green hat and cream pearls from one Seedream 5.0 Pro prompt. Name any colours you know.

Can I colorize a photo on my iPhone?

Yes, in your iPhone's browser — there's no app to install. Photograph the print flat in even light without glare, open the Kenerate web app, upload the photo and ask Seedream 5.0 Pro for natural colours while keeping every face the same. Download the result to your photos and keep the original scan as well.

How do I restore an old photo fully?

Scan it, repair it, colorize it if you like, then upscale it for printing. Our guide to restoring old photos covers scanning, repair and printing tips in detail. Photograph or scan the print flat in even light, ask for repairs and colour in one Seedream 5.0 Pro prompt, upscale small prints, and always keep the original scan.

Colorize Photo with AI, explained

What works, what to avoid, and how to pick a model.

How AI colorization works

Image models have learned what colours objects usually have — skin, sky, grass, fabrics. When you ask for colour, the model repaints the grayscale image with plausible tones while keeping the shapes, which is why it's important to ask it to keep faces the same.
