How to Fix OneNote High Contrast Mode Showing Gray Text
Question details
The user needs to resolve an issue where enabling a Windows high-contrast theme causes OneNote to display text, colors, and highlights in gray, limiting normal formatting and readability.

- Product
- Microsoft OneNote
- Device & OS
- Windows
- Scenario
- Using Microsoft OneNote while a Windows high-contrast theme is active for better screen visibility.
- Observed behavior
- Text, colors, and highlight formatting appear entirely in gray, making it difficult to distinguish colors and select text normally.
Ensure you have administrative access to your Windows system settings, as fixing this requires adjusting system-wide accessibility and contrast themes.
Select or Customize a Different Windows High Contrast Theme
Because OneNote inherits its visual constraints from Windows, changing to a different built-in contrast theme or manually customizing its colors can restore text and highlight visibility.
Windows offers several built-in high-contrast themes (such as Aquatic, Desert, Dusk, and Night sky). Switching between these or tweaking the specific color values for text and hyperlinks can largely bypass the gray-out effect in OneNote.
Press the Windows Key + I to open Settings, then click on 'Accessibility' (or 'Ease of Access' in older Windows versions).
Select 'Contrast themes' (or 'High contrast') from the left-hand menu or main list.
Click the drop-down menu under the contrast themes section and select a different theme, such as 'Night sky' or 'Desert', then click 'Apply'.
If OneNote text is still gray, click 'Edit' next to your chosen theme. Adjust the colors specifically for 'Text', 'Hyperlinks', and 'Selected Text' to make them more distinct, then save and apply.

Temporarily Toggle Off High Contrast Mode
If customizing the theme does not provide the exact color accuracy you need in OneNote, you can quickly toggle off the high contrast mode using a keyboard shortcut while formatting your notes.
Experience Better Document Accessibility with WPS Office
If Microsoft Office applications are causing display conflicts with your system themes, consider switching to WPS Office. It provides robust, independent reading modes and eye protection features without compromising your Windows visual settings.
- 1. Download and Install: Visit the official WPS website to download and install WPS Office for free on your Windows device.
- 2. Open Your Documents: Launch WPS Office and open your notes, documents, or spreadsheets directly from the dashboard.
- 3. Enable Eye Protection Mode: Navigate to the 'View' tab on the top ribbon and click on 'Eye Protection Mode' or 'Dark Mode' to comfortably view your text with optimal contrast.

Frequently Asked Questions
Why does OneNote turn my text and highlights gray?
When Windows High Contrast Mode is enabled, OneNote automatically overrides its native formatting to comply with the OS theme. This is designed to maximize contrast globally but often results in uniform gray text and highlights within the application.
Can I keep High Contrast Mode on but disable it only for OneNote?
No, Windows High Contrast Mode applies system-wide and cannot be disabled for individual applications. However, you can use the 'Left Alt + Left Shift + Print Screen' shortcut to quickly toggle it on and off when you specifically need to view OneNote in its standard colors.
Will customizing the Windows theme fix the text selection issue in OneNote?
Yes, modifying the 'Selected Text' color in your Windows High Contrast settings can make highlighted or selected text in OneNote much easier to read and identify, solving the issue of gray-on-gray highlights.
