What this tool does
Highlight a blue object or a red accessory in an otherwise monochrome scene.
Useful limitations
Hue ranges overlap; objects of similar hue are treated together and neutral pixels may change. Browser decode support and color profiles vary, and local device memory limits apply. For animation, only one still frame is used.
Privacy and compatibility
The selected file is read locally with browser APIs. It is not sent to this website’s server. Outputs are generated locally; some exports become PNG, text/JSON or single-page PDF according to the tool. Keep an unedited original and check the result carefully.
