What this tool does
Neutralize a broad red, green, or blue cast using a measured gray-world correction with adjustable strength and local processing.
Decode → validate options → process pixels on canvas → encode a new output Blob
Processing stays in this browser tab. Very large images can exceed the memory available on phones or older computers.
Supported formats
The tool accepts browser-decodable still images. Animated input is handled as a single displayed frame. SVG is not accepted for pixel tools because safe rasterization varies by browser.
| Format | Support |
|---|---|
| PNG | Supported |
| JPEG | Supported where the tool does not require transparency |
| WebP | Supported when decoded by the browser |
Tips for better results
- Keep an untouched copy of the source image.
- Inspect edges, fine text, and gradients at full size.
- Use a smaller source if the browser reports a memory limit.
FAQ
How does gray-world color cast correction work?
It measures average red, green, and blue values, then scales the channels toward a shared neutral average.
Will this correction work on sunset photos?
It can remove intentional warm color, because the method assumes the overall scene should average toward neutral. Reduce the strength for stylized lighting.
Why did a mostly blue image become too warm?
A scene dominated by one real color violates the gray-world assumption. This tool works best when the photo contains varied colors and neutral objects.
Can I control how much cast is removed?
Yes. Strength blends the measured correction with the original image from 0 to 100 percent.
Does this replace a calibrated white-balance workflow?
No. It is a practical browser correction, not a RAW converter or ICC-managed color workflow.
