Extract dominant colors from an image—build schemes on color palette or convert on color converter.

About Image color palette

Extract dominant hex colors from an uploaded image—canvas sampling in the browser; not a harmony generator. The interactive transform on this page runs in your browser tab—Toolcore does not need your paste for the core operation described above.

How to use this page

Paste or type in the main workspace, run the primary action from the toolbar, then copy or download the result. Use Load example when the page offers it, or URL prefill (?q= / ?qb=) so agents and tickets open the same input.

Sample colors from a photo or graphic—then tune schemes on color palette or convert on color converter.

Image

?

The image is downscaled in your browser before sampling—nothing is uploaded. Transparent areas are skipped.

Nearby workflows on Toolcore

  • Image text watermark — Overlay semi-transparent text on PNG or JPEG with canvas—position, opacity, and size—local only. after you export or copy from the media workspace.
  • Color converter — HEX, RGB, HSL, OKLCH, named colors—paste a CSS color or use harmonic palette hints. after you export or copy from the media workspace.
  • Harmony color palette — Complementary, split, triadic, analogous, tetradic, and monochromatic sets from one CSS color—HEX copy and :root variables. after you export or copy from the media workspace.

Common use cases

  • Pull brand-like colors from a logo screenshot before building a theme.
  • Sample hero photography to seed a landing-page palette.
  • Quickly list hex values from UI mock exports for design tokens.

Common mistakes to avoid

  • Confusing with harmony palette tools

    This reads colors from pixels; the Color hub palette page generates schemes from a single picked color.

  • Expecting print-perfect accuracy

    Downscaled sampling and bucketing approximate dominance—verify critical brand colors manually.

FAQ

Is my image uploaded?

No—decoding and canvas sampling run locally in your browser.

Transparent PNGs?

Pixels with low alpha are skipped so backgrounds do not skew results.
