What is a Color Palette Extractor?
A color palette extractor analyzes an image and identifies the most prominent colors present. It samples pixels across the image, groups similar colors together, and ranks them by frequency. The result is a palette of dominant colors that represent the image's overall color scheme.
This tool uses the HTML5 Canvas API to read pixel data directly in your browser. Your image is never uploaded to any server.

Frequently Asked Questions
How does the color extraction work?
The tool samples pixels from across the image, groups them by color similarity, and ranks them by frequency. It then selects the most dominant colors to form the palette. This process runs entirely in your browser.
How many colors can I extract?
You can choose between 3 and 12 colors. The tool will display the most dominant colors within your selection. Fewer colors gives a simpler palette; more colors provides more nuance.
What color formats are shown?
Each color displays its HEX (e.g., #FF5733), RGB (e.g., 255, 87, 51), and HSL (e.g., 11, 100%, 60%) values. You can click the HEX value to copy it to your clipboard.
Can I download the palette?
Yes. You can download the palette as a PNG image showing all color swatches with labels. You can also copy CSS custom properties (—color-1 through —color-N) for easy integration into your web projects.
Is this tool safe?
Yes. All processing is done in your browser using the HTML5 Canvas API. Your image is never uploaded to any server, stored, or logged.
