Color picker for Chromebook
ChromeOS has no built-in system color picker, and school or work Chromebooks often block extension installs. Chrome on ChromeOS does ship the EyeDropper API (Chrome 95+), so a web page can hand you a pixel-accurate eyedropper with no install and no admin approval.

One quick heads-up
How screen capture works
After you click Continue, your browser will switch focus to the window you're sharing. Press Alt + Tab to come back here — your captured frame will be waiting.
How to do it
- Open this site in Chrome on your Chromebook.
- Click “Pick a color”. The cursor turns into a magnified loupe.
- Move over any pixel on screen, including Android apps, the Files app or a Linux (Crostini) window, and click.
- Copy the HEX, RGB, HSL or OKLCH value with one click. It's also saved to your local palette.
Tips and gotchas
- On a managed Chromebook, admin policy can block extensions but usually not ordinary websites, which is why a web-based picker still works.
- Install the site as an app (Chrome menu → Install) to launch it from the shelf like a native tool.
- If the eyedropper cancels, the window probably lost focus. Click the button again and pick without switching windows.
- In tablet mode with no mouse or trackpad, the live picker can't hover. Use screenshot mode instead.
FAQ
Does ChromeOS have a built-in color picker?
Not a system-wide one. Some individual apps have their own, but there is no OS-level eyedropper. Chrome's EyeDropper API fills that gap from inside a web page.
Will this work on a school Chromebook?
Usually, yes. It's a normal website with no extension to install. Some schools block specific domains through a filter; if this site is blocked, ask your admin.
Can I pick colors from Android apps on my Chromebook?
Yes. The EyeDropper samples whatever is composited on screen, so Android and Linux app windows are fair game as long as they're visible when you click.
