Your Excel screen may suddenly appear in black and white or with harsh color changes. This is almost always caused by Windows High Contrast mode being activated. High Contrast is an accessibility feature that changes system colors to improve visibility. This article explains how to quickly turn off High Contrast mode to restore Excel’s normal color scheme.
Key Takeaways: Restoring Color in Excel
- Left Alt + Left Shift + Print Screen: This keyboard shortcut toggles High Contrast mode on and off in Windows.
- Windows Settings > Accessibility > Contrast themes: The central control panel for managing all High Contrast settings.
- Excel Options > General > Personalize your copy of Microsoft Office: Verify Office is not using a custom high contrast theme.
Why Excel Displays in Black and White
Excel does not have a standalone setting to turn the entire interface black and white. When this happens, Excel is responding to a system-wide command from Windows. The High Contrast accessibility feature overrides the default color palette of applications. It uses a limited set of colors to make text and UI elements stand out.
This mode can be triggered intentionally via settings or accidentally by a keyboard shortcut. It affects all open windows, not just Excel. The change is immediate and can make charts, cell shading, and ribbon icons appear monochrome. Understanding that this is a Windows setting is the key to fixing it quickly.
Steps to Turn Off High Contrast Mode
Use the quick keyboard method first. If that does not work, proceed to the full settings menu.
Method 1: Use the Keyboard Shortcut
- Press the toggle keys
Simultaneously press the Left Alt key, the Left Shift key, and the Print Screen key on your keyboard. You may hear a sound or see a confirmation dialog. - Confirm the change
If a dialog box appears asking to turn on or off High Contrast, select “No” or press Escape to cancel and disable it. The screen colors should revert instantly.
Method 2: Disable High Contrast in Windows Settings
- Open Windows Settings
Click the Start menu and select the Settings gear icon. You can also press the Windows key + I on your keyboard. - Navigate to Accessibility settings
Click on “Accessibility” in the left sidebar. Then select “Contrast themes” from the list of options on the right. - Turn off the contrast theme
You will see a toggle switch labeled “Contrast themes.” If it is set to “On,” click it to turn it off. The screen will flash as colors return to normal. - Select the default theme
In the drop-down menu above the toggle, ensure “None” is selected. Close the Settings window.
Method 3: Check Excel and Office Themes
- Open Excel Options
In Excel, go to File > Options. This opens the Excel Options dialog box. - Go to the General tab
In the left pane of the dialog, click on “General.” Look for the section titled “Personalize your copy of Microsoft Office.” - Verify the Office Theme
Click the drop-down menu next to “Office Theme.” Make sure “Colorful” or “White” is selected, not “Dark Gray” or “Black.” Click OK to apply.
If Colors Do Not Return to Normal
If the screen remains black and white after trying the steps above, a different system setting may be active.
Windows Color Filters Are Active
Windows has a separate feature called Color filters. It can apply grayscale or other filters. Press Windows key + Ctrl + C to toggle color filters on and off. Alternatively, go to Settings > Accessibility > Color filters and turn the switch off.
Display Driver or Monitor Issue
A faulty graphics driver or monitor cable can cause color loss. Restart your computer first. If the problem persists, open Device Manager, find your display adapter, and update the driver. Check your monitor’s built-in menu for any color mode settings.
Excel in Safe Mode
To rule out an Excel add-in causing display issues, start Excel in Safe Mode. Hold the Ctrl key while clicking the Excel icon. If colors are normal in Safe Mode, an add-in is likely causing a conflict. Disable add-ins via File > Options > Add-ins.
High Contrast Mode vs. Color Filters: Key Differences
| Item | High Contrast Mode | Color Filters |
|---|---|---|
| Primary Purpose | Accessibility for low vision, changes UI element colors | Color blindness assistance, applies tint or grayscale to entire screen |
| Activation Shortcut | Left Alt + Left Shift + Print Screen | Windows key + Ctrl + C |
| Settings Location | Settings > Accessibility > Contrast themes | Settings > Accessibility > Color filters |
| Effect in Excel | Changes ribbon, cell grid, and dialog box colors to a preset theme | Applies a uniform color filter over the entire application window |
| Customization | Allows creation of custom contrast themes with specific colors | Offers preset filters like Grayscale, Inverted, or Deuteranopia |
You can now restore Excel’s full color display by disabling High Contrast mode. Use the Left Alt + Left Shift + Print Screen shortcut for the fastest fix. For more permanent control, adjust the settings in Windows Accessibility. Explore the Color filters menu if you need different types of visual assistance without the stark black and white theme.
