Quick answer

Updated

Kenerate colorizes black and white photos with AI: upload the photo and ask for natural colours — the model adds realistic skin tones, clothing and scenery colours and can repair scratches, creases and fading in the same step, keeping every face the same. Seedream 5.0 Pro (2K output, up to 10 reference images) gave the most natural results in our tests on four old photos. A free account gets 25 free credits.

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.

In depth

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.

Preserving the original

Always keep the original scan. Treat the colour version as an interpretation, especially for family history.

    How do I colorize a black and white photo?
