Question 1

How does palette extraction work?

Accepted Answer

The tool samples the image at a lower resolution, then applies a k-means-style color clustering algorithm to group similar pixels. The largest clusters become the dominant colors in the palette. This works well for photos, illustrations, screenshots and design mockups.

Question 2

Can I use any image URL?

Accepted Answer

Most public image URLs work, including direct links to PNG, JPG, WebP and GIF files. Some servers block cross-origin image loading (CORS), in which case you may need to download the image and use the upload tool. Picsum, Unsplash, Wikipedia and most CDNs work.

Question 3

What can I do with the extracted palette?

Accepted Answer

You can copy individual color codes, export the palette as CSS custom properties, JSON array, or as a PNG swatch image. Designers use palettes to build mood boards, design systems, color schemes for websites, app themes, and brand identity work.

Question 4

Are my images uploaded to a server?

Accepted Answer

No. Color extraction happens entirely in your browser using the HTML5 Canvas API. The image URL is only loaded by your browser — nothing is sent to any server.
