Image Color Extractor
Extract dominant colors from any image instantly. Get HEX codes for your palette.
① Upload an image ② Adjust the number of colors ③ Click any swatch to copy the HEX
How does color extraction work?
This tool extracts dominant colors from images using a pixel sampling algorithm. The image is drawn to a Canvas element, pixels are sampled at regular intervals, and similar colors are grouped using color quantization. The result is a palette of dominant colors with their HEX codes. The number of colors can be adjusted from 3 to 12. All processing happens client-side — your image is never uploaded to any server.
Frequently Asked Questions
The tool uses HTML5 Canvas to sample pixels from the image at regular intervals. Similar colors are grouped together using color quantization (merging nearby colors in RGB space). The most common color groups become the extracted palette. More samples = more accurate results but slower processing.
Images contain thousands of unique colors. Color extraction groups similar colors together (quantization) to reduce them to a manageable palette. The algorithm prioritizes the most dominant (most frequent) colors. Gradients and photographic images naturally produce smooth color distributions that are harder to precisely capture.
For brand color identification: 5-8 colors. For UI design inspiration: 6-10 colors. For a minimalist summary: 3-5 colors. More colors (10-12) capture subtle variations but may include similar shades that are hard to distinguish. Fewer colors (3-5) give clear, distinct dominant hues.
All image formats supported by your browser work. For color extraction: PNG and WebP give the most accurate colors (lossless). JPG adds compression artifacts that can slightly affect extracted colors. GIF files are limited to 256 colors. SVG is rasterized to pixels before extraction.
Yes. This tool is useful for: reverse-engineering brand palettes from logos, extracting colors from design references, creating color schemes from photography, and checking color usage in existing designs. Always verify extracted colors against the original design files when precision matters.
Click any color swatch to copy its HEX code, then use it in CSS: color: #hexcode; or background: #hexcode;. You can also use the crosslinks to explore tints & shades of extracted colors or generate complementary palettes.
There is no hard limit, but very large images (over 10MB) may be slow to process as all pixel sampling happens in the browser. For faster extraction, images are internally downscaled to a maximum of 200×200px for the sampling algorithm — the full-resolution image is still displayed for preview.
