Extract dominant colors from an image: the complete guide
Whether you are a graphic designer, a front-end developer or simply curious about the colors in a photo, palette extraction is an essential tool. Here is everything you need to know.
Why extract colors from an image?
For designers
Building a consistent visual identity inspired by an existing image (nature photo, artwork, product) ensures visual harmony across all media.
For developers
Getting HEX, RGB or HSL codes directly from an image avoids back-and-forth between Photoshop and the code editor.
For branding
Identifying the exact colors of a logo or brand photo to faithfully reproduce them in all communication materials.
How does color extraction work?
Our Color Palette tool uses the median cut algorithm, a classic color quantization technique:
- Collection: all pixels in the image are analyzed.
- Grouping: similar pixels are grouped into "buckets."
- Representation: each bucket is represented by its average color.
- Sorting: colors are ranked by frequency of occurrence.
Using the palette tool
- Go to webfiletools.com/en/palette-image.
- Choose the number of colors you want (2 to 12).
- Drop your image (PNG, JPEG, WebP, GIF…).
- Click a color to copy its HEX code.
- Use "Copy all HEX" to export the full palette.
Color formats explained

| HSL | hsl(217, 91%, 60%) | Modern CSS, animations |
Creative tips
- Nature photography: natural palettes (earth tones, forests, skies) are very on-trend for modern interfaces.
- Artworks: extract the palette from a master painting to create an original theme.
- Product packaging: analyze a competitor's product colors to differentiate yours.
