Image Color Palette Generator
Sample the dominant colours in a photo (simple quantization, not a design-system extractor).
Image Color Palette Generator is its own job in the catalog (developer): Sample the dominant colours in a photo (simple quantization, not a design-system extractor). It is not a copy of the resizer or converter with a new title — the operation is “palette”.
