Apply a controlled two-tone palette without uploading the image.
This is controlled duotone colorization, not a claim to reconstruct historically accurate object colours.
About the Photo Colorizer
Photo Colorizer maps every pixel's perceived brightness between selected shadow and highlight colours, preserving the original photograph's light and dark structure.
It provides intentional artistic colorization rather than pretending to infer historically accurate colours that are not present in the source.

Frequently asked questions
- Are the colours historically accurate?
- No. This tool creates a controlled two-tone treatment and does not guess original object colours.
- Can I create sepia?
- Yes. Choose dark brown shadows and warm cream highlights.
- Is the photo uploaded?
