The best color picker depends on your operating system. Mac has one built in that most people don't know about. Windows has a free Microsoft tool. Linux has open-source options. And browser tools work on all of them.
| Platform | Best Free Tool | How to Access | Formats |
|---|---|---|---|
| macOS | Digital Color Meter | Applications > Utilities (pre-installed) | RGB, hex (via display setting) |
| Windows 10/11 | PowerToys Color Picker | Win+Shift+C (install PowerToys first) | Hex, RGB, HSL, CMYK, and more |
| Ubuntu/Debian | Gpick | apt install gpick | RGB, hex, HSL, CMYK |
| Fedora/RHEL | Gpick | dnf install gpick | RGB, hex, HSL, CMYK |
| KDE Linux | KColorChooser | Pre-installed in KDE | RGB, hex, HSL |
| Chromebook | Browser color picker | Open in Chrome — no install | Hex, RGB, HSL |
| Any platform | Online Color Picker | Open in any browser | Hex, RGB, HSL |
Every Mac ships with Digital Color Meter. Most Mac users don't know it exists.
It's simple, it's free, and it's already on your Mac. For more features (menubar integration, history, palette saving), Sip costs $10 one-time.
Microsoft's own PowerToys suite includes the best Windows color picker available.
Works system-wide — any application, any window. The keyboard shortcut makes it instant.
Linux color picker options depend on your desktop environment:
| Capability | Desktop App (PowerToys, DCM, Gpick) | Browser Tool |
|---|---|---|
| Sample any pixel on screen | ✓ Yes — hover over any window | ✗ No — works within the browser page |
| Pick color from wheel/spectrum | ~Some support this | ✓ Yes — visual color selection |
| Convert between formats | ✓ Most show multiple formats | ✓ Shows hex, RGB, HSL simultaneously |
| One-click copy | ✓ Keyboard shortcut | ✓ Click the code to copy |
| Works without installation | ✗ Requires install (except Mac DCM) | ✓ No install needed |
| Works on Chromebook/tablets | ✗ No | ✓ Yes — any browser |
| Works on locked-down work PCs | ✗ May need admin rights | ✓ Just open a website |
| Extract from images | ✗ Samples screen pixels only | ✓ Use Color Extractor |
Best approach: Use the desktop tool for sampling colors from your screen. Use the browser tool for format conversion, picking new colors, and working on devices where you can't install apps.
Pick colors on any device — Mac, Windows, Linux, Chromebook, mobile.
