Extract a deterministic median-cut palette with sample shares and HEX, CSS and JSON downloads.

Result
Enter your data or use the example, then run the tool.
Worked example
The sample is half opaque red and half opaque blue. Two colors return #ff0000 and #0000ff at 50% of non-transparent samples each.
Method
Sample proportionally at no more than 256 × 256. Ignore fully transparent pixels and composite partial transparency against the selected background. Deterministic weighted median-cut groups the RGB samples and reports representative colors and shares.
Limits
This is a downsampled approximation, not color calibration or a print-profile tool. ICC/HDR handling and scaling can alter colors. An entirely transparent image is rejected. Static input is limited to 20 MiB and 40 million pixels.
