About this tool
Replace a chosen uniform background color locally with feathered color-distance matching.
Even lighting and strong subject contrast produce cleaner edges.
This tool performs deterministic chroma keying rather than AI subject segmentation.
Frequently asked questions
Does this recognize the subject automatically?
No. It replaces pixels based on color similarity, so it works best with uniform studio or green-screen backgrounds.
What does tolerance change?
Higher tolerance replaces a wider range of shades near the selected source color.
Why can subject colors change too?
If the subject contains colors close to the selected background, color-key replacement cannot distinguish them semantically.
