Quilt Color Randomizer

How to use this tool

Map fabric labels to colors, lock selected mappings and preview a repeated patchwork pattern.

1. Enter a rectangular grid of labels A–H; matching labels share one fabric color.
2. Set or lock fabric colors and randomize the remaining mappings.
3. Save and restore the pattern on this device, or export its SVG, PNG and JSON mapping.

About the results

This version uses square blocks in a label grid. It is not a complete quilt-layout editor, fabric inventory service or cutting calculator. Colors are screen approximations; saved patterns stay in this browser.
