How it works

Complete the job in three clear steps

  1. Add one JPG, PNG, WebP, or BMP image to the local workspace.
  2. Choose the relevant settings and create a ranked palette and CSS variables.
  3. Review the local result, then copy or download it before leaving the page.

Important

Check the result before relying on it

Keep an untouched copy of important source files. Browser processing depends on available device memory, and you should inspect every downloaded result before deleting the original.

Questions

About this tool

Does Lucaden upload my images?

No. The pinned open-source runtime processes temporary image data in this browser, and this tool has no upload step.

What should I verify?

Extracted colors are starting points, not a complete design system. Review visual hierarchy, brand requirements, and accessibility before use.

Which open-source project powers this tool?

The implementation uses Color Thief (MIT runtime 3.5.0). Upstream projects retain their original names, copyrights, and licenses.
