Why it's a strong pick

Chromapicker does more than a plain eyedropper. It is free and open source under the MIT license, and it uses Manifest V3. It is a young project with one maintainer, mthcht. The repo's latest commit is from April 2026, a README edit, so we do not count it as a release date. Its manifest lists no host permissions.

What it does

Chromapicker is a color picker and palette tool for Chromium browsers. Pick a pixel with the browser's EyeDropper and the hex value is copied for you. You can also pull every color from a page, or build a palette from a local image.

Key features

  • Pixel picker. Uses the browser's native EyeDropper, with Alt+P and auto-copy of hex.
  • Page colors. Extract all colors used on a page, and highlight the elements that use one.
  • Image palettes. Make a palette of 3 to 12 colors from a local image.
  • Mixer and harmonies. Mix in RGB, HSL or OKLCH, and generate harmonies.
  • Gradients and history. Build CSS gradients and keep your last 24 picks.

Who it's for

Chromapicker is for designers and front-end developers who want more than a basic eyedropper. If you only need one hex code now and then, a simple picker may be enough. It also shows a P3 gamut indicator for wide-gamut work.

What permissions does Chromapicker ask for?

Its manifest asks for storage, clipboardWrite, scripting and activeTab. It lists no host permissions. The README permissions table matches. The README says there is no telemetry, analytics, account or cloud sync, which is the developer's own claim. One exception it discloses: the popup loads a Google font, so a request to Google happens when it opens.

Where is my color history kept?

The README says your history is kept in chrome.storage.local, which is storage inside your browser. It also says image palettes are processed locally. These are the developer's own claims. The same README discloses the Google font request when the popup opens.

Does it pick wide-gamut colors?

Not fully. The native EyeDropper returns colors clamped to sRGB, so wide-gamut colors are lost. The README tells you to use DevTools for those. The extension does show a P3 gamut indicator, but treat picked values as sRGB, and do not expect it to return the full range of a wide-gamut color.

FAQ

Is it free? Yes. It is open source under the MIT license.

Is it a new project? Yes. The manifest is version 1.0.0, there are no releases, and there is one maintainer.

What is the shortcut? Alt+P starts a pick.

Good to know

For colors set in a stylesheet, use the page-color extraction instead of the eyedropper. It reads computed styles and SVG fills. Use DevTools when you need exact wide-gamut values.

Other color pickers to compare

Chromapicker is one of 5 picks in our color pickers guide:

  • ColorZilla: A color picker, eyedropper and gradient generator with a webpage color analyzer, for Chrome and Firefox.
  • Eye Dropper: A plain color picker for Chrome. Click a color on a page and copy it as HEX, RGB, HSL or HSV.
  • ColorPick Eyedropper: A focused eyedropper with a zoomed, draggable magnifier. Open source, and it works without registration.
  • Site Palette: Pulls a color palette from a whole web page, then exports it to Figma, Sketch, Adobe Swatch or SVG. Has a trial and paid plans.
