- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Attempting to improve visual clarity and contrast for better accessibility after a software interface update.
- Observed behavior
- Recent Microsoft 365 updates introduced pastel colors and transparency effects, which reduced visual contrast and made navigation difficult for users with visual impairments.
Before adjusting settings, confirm your Microsoft 365 applications are fully updated, as Microsoft occasionally releases patches that address widespread usability and interface feedback.
Change the Microsoft 365 Office Theme
Switching your built-in Office Theme to a darker or higher-contrast option is the most direct way to eliminate transparent pastel colors.
Microsoft 365 includes several built-in themes that alter the appearance of your ribbon, backgrounds, and selected items. Changing this setting will apply across all installed desktop Office applications.
Launch any desktop Microsoft 365 application (such as Excel or Outlook). Click on 'File' in the top-left corner, then select 'Options' at the bottom of the left-hand menu.
In the Options dialog box, stay on the 'General' tab and scroll down to the 'Personalize your copy of Microsoft Office' section.
Click the drop-down menu next to 'Office Theme' and select 'Black', 'Dark Gray', or 'White' to improve contrast. Click 'OK' to save your changes.
Enable Windows High Contrast Settings
Use your system-level Windows accessibility settings to force a high-contrast environment across all software, including web-based Office apps.
Submit Feedback for Accessibility Concerns
Since permanent rollbacks of interface updates are generally unavailable, reporting the issue helps Microsoft improve future accessibility features.
Switch to WPS Office for a Clear, Customizable Interface

- 1. Download WPS Office: Visit the official WPS website and download the free installation package for your operating system.
- 2. Install the Software: Run the installer and follow the on-screen instructions to quickly set up WPS Office on your computer.
- 3. Open Your Documents: Launch WPS Office and open your existing Word, Excel, or PowerPoint files directly without any formatting loss.

Frequently Asked Questions
Can I permanently rollback to the old Microsoft 365 interface?
Permanent rollbacks to older interface versions are generally unavailable. Microsoft 365 is updated according to your specific license and update channel, making downgrades temporary or impossible for most users.
Why are unread messages hard to see in Outlook?
Recent Microsoft updates introduced pastel colors and transparency effects which lower visual contrast. To fix this, you can change your Office Theme to Dark Gray or Black via File > Options > General.
Do Windows display settings affect Microsoft 365 web apps?
Yes. Browser and web-based Office applications typically inherit your system's Windows display and high-contrast settings, as well as any specific appearance settings configured in your browser.
Will disabling Office updates fix the contrast issue?
Disabling updates via File > Account is not recommended. While it stops future interface changes, it also prevents your device from receiving critical security patches and performance fixes.
