What Is an Image Color Extractor?
An image color extractor analyzes a photograph or graphic and identifies the dominant colors. Upload any image and this tool samples its pixels with the Canvas API, groups similar shades into buckets, and outputs a ranked palette of the most prominent colors, with HEX, RGB and HSL values and exports for CSS, Tailwind and JSON.
Use Cases
Brand design — extract a palette from product photography or mood boards to build cohesive brand colors. Web design — pull colors from a hero image to create a matching UI. Dynamic theming — programmatically extract the dominant color from user-uploaded images for personalized interfaces. Art direction — analyze film stills, paintings, or photography for color inspiration.
How to Use This Image Color Extractor
- Upload an image — Select or drag-and-drop any JPEG, PNG, or WebP image.
- View the extracted palette — The tool analyzes the image and extracts the dominant colors, ordered by prominence.
- Copy individual colors — Pick HEX, RGB or HSL, then click any swatch to copy that value to your clipboard.
- Export the palette — Copy all colors as CSS custom properties, a Tailwind v3 config, a Tailwind v4 @theme block, JSON with each color's share of the image, or a plain list of hex codes.
Tips and Best Practices
- → Use photos as palette inspiration. Upload landscape photos, artwork, or product images to extract natural, harmonious color palettes for your designs.
- → Extract brand colors from logos. Upload a client's logo: flat fills come back as their exact values, because each palette color is the average of identical pixels. Use a large, clean PNG or SVG export rather than a compressed JPEG, which shifts colors slightly.
- → Combine with our Palette Generator. Start with extracted colors and expand them into a full design palette with complementary and accent colors using our Palette Generator.
- → Higher-contrast images yield better palettes. Images with distinct color regions produce clearer, more usable palettes. Low-contrast or muted images may extract many similar shades.
- → Turn a palette into a film grade. Once you know an image's dominant colors, recreate that mood on your own photos with Cinematic Looks — one-click film grades you can export as a .cube LUT.
Frequently Asked Questions
How does color extraction work?
The tool draws your image onto a hidden canvas scaled so its longest side is at most 200 pixels, samples about 10,000 of those pixels, and sorts each one into a 16 by 16 by 16 grid of color buckets. Buckets are ranked by how many pixels they hold, and each palette color is the average of the real pixels in its bucket. A color that is too close to one already in the palette is skipped, so the palette favors distinct colors over near-duplicates.
What image formats are supported?
Anything your browser can display as an image: PNG, JPEG, WebP and GIF (only the first frame of an animated GIF is read), plus AVIF in browsers that support it. Processing happens locally in your browser and no image is uploaded to any server.
How can I use extracted colors?
Build website color schemes from photography, create brand colors from product images, generate design tokens from mood boards, or find dominant colors for dynamic theming.
What is k-means clustering and how does it group colors?+
K-means picks a set number of center colors, assigns every pixel to its nearest center, moves each center to the average of its pixels and repeats until the centers settle. This tool does not use k-means or median cut. It uses fixed buckets, which is faster and gives the same palette every time for the same image: pixels are grouped by their position in a 16-step grid per channel, the fullest buckets win, and each bucket reports the average of the pixels inside it. The trade-off is that a color sitting on a bucket boundary can be split across two neighbours, which the distinctness filter then usually merges by skipping the second.
How many colors does the extractor find?+
You choose 6, 8, 10 or 12; 8 is the default. The palette can come back shorter when the image has fewer distinct colors than that, because near-duplicates are skipped. On a flat graphic with three colors, the extra slots fill with antialiased edge pixels, which are blends of the real colors, so pick the smallest count that covers what you see.
Can I extract colors from a website screenshot?+
Yes, take a screenshot and upload it. This is a quick way to analyze a competitor's color palette or identify colors from any visual source. For live websites, browser DevTools can also inspect CSS color values directly.
Which pixels does the extractor look at, and can it miss small accents?+
It reads a copy of the image scaled down to at most 200 pixels on the longest side and samples about 10,000 of its pixels, skipping any that are more than half transparent. Ranking is by area, so a small accent such as a thin logo outline or a single red button may fall below the cutoff. Raise the count to 10 or 12 to catch it, or crop the image to the area you care about.
Why do my extracted colors look slightly different from the original image?+
On flat areas they should match exactly, because each palette color is the average of the pixels in its bucket and a flat fill averages to itself. Gradients, photos and soft shadows are different: the bucket average is a representative color that may not exist verbatim in the image. Antialiased edges and JPEG compression also add in-between shades. For one exact pixel, use an eyedropper such as the Color Picker on the original.
