The practical guide

Turn an image into a reusable palette instead of an unexplained row of swatches.

The generator samples decoded pixels locally, groups nearby colors into quantized bins, ranks those groups by sampled frequency, and filters near-duplicates before presenting the selected palette.

01

Dominant colors with an honest frequency estimate

Each swatch includes an approximate share of sampled pixels. The percentage describes the grouped sample, not an exact count of every unique source pixel.

02

Use the palette in design and code

Copy individual HEX values, sort by frequency or luminance, copy CSS custom properties, or download structured JSON and a labeled PNG swatch strip.

03

Check contrast before choosing text

The reported white and black contrast ratios use relative luminance as a quick design aid. They do not replace checking complete components, font sizes, states, and current WCAG requirements.

04

Palette generator versus color picker

A palette summarizes prominent color groups across the image. Image Color Picker is the better tool when you need the exact rendered RGB value at one chosen pixel.

Questions, answered

Frequently asked questions

Does it return HEX, RGB, and HSL?

Yes. Every swatch displays all three formats and can be exported in JSON.

Are these exact color percentages?

No. They are approximate frequencies from sampled and grouped pixels, which keeps analysis responsive on large images.

Why are similar colors combined?

Quantization and a diversity threshold prevent a palette from being dominated by nearly identical shades.

Can I export the palette?

Yes. Copy CSS variables or download JSON and a labeled PNG swatch strip.

Does the image leave my device?

No. Decoding, sampling, grouping, and export happen in this browser.
