Frequently Asked Questions

  • How do I extract dominant colors from an image online?

    Upload your image to ToolBox Image Dominant Color Extractor, click "Extract Palette", and instantly see the dominant colors with HEX codes, RGB values, and percentage coverage. Adjust the color count (3-12), toggle exclude white/black filters, and click any color to copy its HEX code. No sign-up, no uploads — completely free and unlimited.

  • What is a dominant color extractor used for?

    A dominant color extractor analyzes an image and identifies the most visually prominent colors. Designers use it to create color palettes from reference images, build brand color schemes from logos, analyze images for design consistency, and extract mood colors from photographs. Developers use it for dynamic theming, generating color-based tags, and image analysis.

  • How does the dominant color extraction algorithm work?

    ToolBox Image's algorithm first downsamples the image to improve performance, then quantizes the colors into discrete buckets. Similar colors are merged together using weighted Euclidean distance, and the remaining colors are sorted by pixel frequency. The result is an accurate palette of the most dominant colors with their relative percentages.

  • Can I customize how many colors are extracted?

    Yes. Use the "Number of Colors" slider to adjust between 3 and 12 colors. The default is 8 colors, which provides a good balance between detail and clarity. More colors capture subtle variations, while fewer colors show only the most dominant tones.

  • What do Exclude White and Exclude Black do?

    The Exclude White toggle removes near-white colors (brightness > 90%) from the palette, which is useful when analyzing images with white backgrounds. The Exclude Black toggle removes near-black colors (brightness < 10%), helpful when analyzing images with dark backgrounds or shadows.

  • Is my image uploaded to a server during color extraction?

    No. All color extraction happens locally in your browser using the HTML5 Canvas API. Your images never leave your device. You can verify this by checking the Network tab in your browser's developer tools — there are zero outbound requests during processing.

  • What image formats are supported for color extraction?

    You can upload JPEG, PNG, WebP, AVIF, and GIF images. The tool works with any image format that the browser can render on a canvas element.
