How AI Photo Colorization Works

Our AI colorization model has been trained on millions of color photographs to learn the relationship between image content and color. It understands that sky tends to be blue, grass is green, and skin tones follow natural patterns — allowing it to make intelligent predictions about what colors belong where in your black and white photo.

The model recognizes faces, sky, vegetation, clothing, buildings, and other common elements in your image and applies colors that match the visual context. A person standing in a park will get natural skin tones, green grass, and blue sky — all without any manual input from you.

Unlike simple color overlay techniques, the AI works at a pixel level, producing smooth, natural-looking colorization without visible borders between colored regions. Gradients, shadows, and lighting are all preserved and enhanced with appropriate color variation.

Will the colors be accurate?
The AI produces natural-looking, contextually appropriate colors. It cannot know the exact original colors (for example, the specific color of a dress), but it will choose realistic and visually pleasing colors that match the content.
What types of photos work best?
Portrait photos, landscapes, street scenes, and family photos produce the best results. The AI handles skin tones, sky, vegetation, and common objects particularly well.
Does colorization cost credits?
Yes, photo colorization uses 2 credits per image. New users get 10 free credits on signup.
What format is the output?
Output is a full-color PNG image at the same resolution as your input.
