Quick answer

Upload an image to extract a compact set of visually distinct dominant colors. You can choose the palette size, sort swatches by frequency, lightness, or hue, edit the result, and export it for design or code.

Quick guide

How to generate a color palette from an image

Turn the dominant colors in a photo, screenshot, or illustration into an editable starting point for a visual system. Image analysis runs locally in your browser.

  1. 1

    Choose an image

    Upload a JPG, PNG, or WebP file. Clear images with a deliberate color range usually produce the most useful palette.

  2. 2

    Review the extracted colors

    Compare the dominant swatches, click a color to pivot the harmony suggestions, and keep the combinations that fit your project.

  3. 3

    Export for your workflow

    Copy individual colors or export HEX, CSS variables, Tailwind colors, JSON, or a PNG reference.

Practical uses

UI and web design

Translate a product image or mood board into background, surface, accent, and supporting colors.

Brand exploration

Build an initial brand-kit direction from photography, packaging, artwork, or an existing visual reference.

Creative production

Keep illustration, social graphics, and presentation assets visually connected to one source image.

Method and accuracy

How this tool works

The browser downsizes the image for bounded work, skips pixels with low alpha, groups nearby samples into a compact histogram, then runs deterministic clustering in the perceptual OKLab space. Cluster centers are converted back to representative sRGB colors and ranked by their sampled frequency. The extraction runs in a Web Worker so it does not block the interface.

Frequently asked questions

Is my image uploaded to a server?

No. The image is decoded and analyzed inside your browser, so the file is not sent to UI Color Picker.

Which image formats are supported?

Use a valid JPG, PNG, or WebP image up to 10 MB. SVG and invalid or unsupported files are rejected.

Which palette export formats are available?

You can export colors as a HEX list, CSS variables, Tailwind configuration, JSON data, or a PNG palette image.
