Solution 1Recommended

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.

1
Open Windows Accessibility Settings

Press the Windows Key + I to open Settings, then click on 'Accessibility' (or 'Ease of Access' in older Windows versions).

2
Navigate to Contrast Themes

Select 'Contrast themes' (or 'High contrast') from the left-hand menu or main list.

3
Change the Built-in Theme

Click the drop-down menu under the contrast themes section and select a different theme, such as 'Night sky' or 'Desert', then click 'Apply'.

4
Customize the Theme Colors

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.

Feature Limitation: Even after customizing the theme colors, OneNote's native highlighting and custom font color features may remain partially limited as long as high contrast mode is enabled at the operating system level.

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.
