If you have trouble seeing things on your computer screen, Windows 11 has a helpful tool called Magnifier. It zooms in on parts of the screen to make things bigger and easier to see.

One useful feature of the Magnifier is Invert Colors. This changes the colors on your screen to their opposite—for example, black turns white, and white turns black. This can make text easier to read and reduce eye strain, especially if you use your computer in a dark room or have light sensitivity.

How to Turn Invert Colors On or Off Using Keyboard Shortcuts

Here’s a quick way to switch invert colors on or off when using Magnifier:

1. Turn on the Magnifier by pressing Windows key + Plus (+).
2. While Magnifier is on, press Ctrl + Alt + I to invert the colors.
3. Press Ctrl + Alt + I again to switch back to normal colors.

This is an easy way to quickly change colors without opening any settings.

How to Turn Invert Colors On or Off Using the Settings App

If you prefer to use Windows Settings, follow these steps:

1. Open the Settings app by clicking the Start menu and then Settings, or press Windows key + I.
2. Click on Accessibility on the left side.
3. Find and click on the Magnifier option on the right.
4. Under the Appearance section, find the Invert colors switch and turn it On or Off.

Close the Settings app when you’re done.

How to Turn Invert Colors On or Off Using the Registry (Advanced)

If you feel comfortable making changes inside Windows system files, you can also turn invert colors on or off by editing the Registry. Please be careful — making wrong changes can cause problems with your computer.

Important: Before you start, back up your registry or create a System Restore point so you can undo changes if needed.

1. Open the Registry Editor by searching for regedit in the Start menu and pressing Enter.
2. Go to this folder path:
   

   ComputerHKEY_CURRENT_USERSoftwareMicrosoftScreenMagnifier

3. Right-click on ScreenMagnifier, choose New > DWORD (32-bit) Value, and name it Invert.
4. Double-click the new Invert entry and set its value to:
   • 1 to turn invert colors ON
   • 0 to turn invert colors OFF
5. Close the Registry Editor and restart your computer for changes to take effect.
