Frequently Asked Questions

How do I extract colors from an image to build a color palette?

Drop or upload any image file to the Color Extractor. The tool samples pixel data from the image using an HTML Canvas, clusters similar colors, and displays the dominant hues as swatches with their hex codes, RGB values, and approximate coverage percentage. Click any swatch to copy the hex value to your clipboard.

Is my image uploaded to a server when extracting colors?

No. The color extraction runs entirely in your browser using the Canvas API’s getImageData() method. The image is loaded into a hidden canvas element, pixel data is read locally, and the clustered colors are computed in JavaScript. No image data is sent to any external server, which is safe for confidential brand assets or private photos.

What image formats can I use with the color extractor?

The tool accepts any image format your browser can decode — typically JPEG, PNG, WebP, GIF, BMP, and SVG raster images. The file is read via the FileReader API and rendered to a Canvas, so the limit is your browser’s native image format support rather than any tool restriction.

How accurate is the color extraction — will it find every shade?

The extractor identifies the most dominant color clusters, not every unique pixel. Images with gradual gradients (like blue skies or skin tones) may be summarized as a few representative hex values rather than every intermediate shade. Photographic images with hundreds of similar hues are simplified to the most visually significant colors for practical usability.

What is a limitation of browser-based color extraction?

Cross-origin images cannot be analyzed due to browser Canvas security restrictions (tainted canvas). If you link to an image hosted on another domain without CORS headers, getImageData() will throw a security error. To work around this, download the image first and upload the local file rather than providing a remote URL.
