| Platform | Screen picker |

| Windows 10/11 | Supported. |
Manual color editing, image import, palette management, and export remain available when screen picking is unavailable.
Download a build for your platform from the Releases page. The macOS .dmg is not Apple-notarized, so the first launch on macOS will show:
"Apple cannot verify that 'OpenColor' is free of malware that may harm your Mac or compromise your privacy."
This is expected for an unsigned open-source app. To open it:
- In Finder, locate
OpenColor.app(after dragging it from the DMG into Applications). - Right-click the app and choose Open from the context menu, then click Open in the dialog.
- macOS will remember the exception for future launches.
Or from the terminal:
xattr -dr com.apple.quarantine /Applications/OpenColor.appOn Windows, SmartScreen may show a similar prompt for the unsigned installer — choose More info → Run anyway.
After the first launch, grant the requested Screen Recording and Accessibility permissions in System Settings → Privacy & Security so the color picker can read pixels and click through the cursor preview.
Requirements: Node.js 18+, pnpm, Rust, and the Tauri prerequisites for your platform.
