Online Image Color Extractor

Extract dominant colors from any image and generate a color palette. This tool uses the median cut algorithm to quantize image pixels and identify the most prominent color clusters. Colors are displayed in HEX, RGB, and HSL formats with one-click copy. All processing happens locally in your browser—your images are never uploaded.

How the Median Cut Algorithm Works

The median cut algorithm divides the color space recursively: it finds the channel (R, G, or B) with the greatest range, sorts pixels by that channel, and splits at the median. This process repeats until the desired number of color buckets is reached. The average color of each bucket becomes one palette entry. This is the same principle used by Photoshop's "Save for Web" palette feature.

How Many Colors to Extract

  • 3-5 colors: Ideal for theme palettes and brand color schemes.
  • 6-8 colors: A balanced default for most design work.
  • 10-12 colors: Full palette analysis for detailed color studies.

If the extracted colors don't match what you see, try increasing the count. Images with rich gradients or gloss effects may produce averaged colors that look different from specific pixels you notice.

Color Extract FAQ

Are the extracted colors accurate?
Yes. This tool uses the median cut algorithm to quantize image pixels, extracting the most prominent color clusters as dominant colors. The algorithm is consistent with Photoshop's "Save for Web" palette principle.
Why do the extracted colors look different from what I see?
Possible reasons: when an image has very rich colors, the algorithm can only capture the most dominant color clusters, and subtle colors may be ignored. Images with strong gradients or gloss may produce averaged colors. You can increase the extraction count (e.g., from 5 to 10 colors) for more comprehensive results.
How many colors can I extract?
You can customize extraction of 3 to 12 dominant colors. Fewer colors work well for theme palettes (e.g., 5 colors), while more colors are suited for full palette analysis (e.g., 10-12 colors).
Are my images uploaded?
No. This tool uses the browser Canvas API to read pixel data and the median cut algorithm to extract colors. All processing happens locally, and your image never leaves your device.
