Color Palette Extractor guide
Extract a compact set of dominant HEX colors from a JPG, PNG, or WebP image directly in your browser.
What this tool does
The Color Palette Extractor loads an image into a small analysis canvas, groups visible pixels into color buckets, ranks those buckets by sampled population, and reports an average color for each leading group. You can request between three and sixteen colors and copy one HEX value or the complete comma-separated palette.
Large images are proportionally reduced so their longest analysis dimension is 200 pixels. This keeps browser processing responsive while maintaining a broad visual sample. Transparent pixels below the alpha threshold are ignored so empty canvas areas do not become a dominant black or transparent result.
The percentages describe the sampled, grouped pixels rather than an exact inventory of every original color. Neighboring shades are intentionally combined. Anti-aliasing, gradients, compression artifacts, lighting, and downsampling can change which representative HEX value is selected.
How to use it
- Select a JPG, PNG, or WebP image.
- Choose how many dominant color groups to return.
- Select Extract dominant colors.
- Review each swatch, HEX value, and approximate sampled share.
- Select a swatch to copy one value or copy the complete HEX list.
Use fewer colors for a concise brand or interface direction. Use more colors when the image includes several products, backgrounds, skin tones, illustrations, or gradual lighting changes.
Benefits
- Produces three to sixteen ranked HEX colors
- Groups neighboring shades instead of listing every pixel variation
- Ignores mostly transparent pixels
- Shows approximate sampled proportions
- Processes the image locally without uploading it
Using an extracted palette
Treat the result as a starting point. Check contrast before using sampled colors for text, buttons, focus indicators, charts, or status messages. A color that is common in a photograph is not automatically accessible against your interface background. Test intended combinations against the accessibility requirements of the project.
Brand files may contain official color values that differ slightly from a screenshot or compressed export. Use the organization’s approved design tokens when they are available. For printed work, HEX represents screen RGB color and does not directly define a CMYK or spot-color result.
The extractor does not identify color names, ownership, brand identity, or licensing rights associated with an image.
