Original PickImageColors source-file lab, 2026-10-25.
Why does an image palette favor the product background?
Run: python reproduce.py --case background-dominant-image-palette --out rerun
Dependency: Pillow. Recorded runtime: Python 3.12.14, Pillow 12.3.0, libwebp 1.6.0.
Measurements are local source-file computations, not browser observations. Library-dependent compression sizes and quantizer choices may change with runtime.
The tool’s existing upload workflow is unchanged; this page does not claim an in-tool crop button. We counted exact flat colors and did not test shadows, antialiasing, object masks or the frequency ranking of a browser palette.
