Scenario

Solution 1Recommended

Enable Windows Dark Mode to Reduce OneNote Brightness

Since OneNote desktop lacks a standalone custom theme generator, you can apply the system-wide Windows Dark Mode to darken the interface and significantly reduce screen brightness.

While you cannot pick specific hex codes for custom theme colors in OneNote, switching to Dark Mode changes the canvas and ribbons to dark gray and black, which is highly effective for reducing eye strain.

1
Open Windows Settings

Click the Start button on your Windows taskbar and select the 'Settings' gear icon, or press the Windows Key + I on your keyboard.

2
Navigate to Personalization

Click on 'Personalization' from the main Settings menu, then select 'Colors' from the left-hand sidebar.

3
Choose App Mode

Scroll down to the 'Choose your default app mode' section and select the 'Dark' radio button. Open OneNote Desktop to verify that the dark theme has been applied.

Frequently Asked Questions

Can I change the page background color in OneNote without using Dark Mode?

Yes. You can change the background color of an individual page by navigating to the 'View' tab on the ribbon and selecting 'Page Color'. This allows you to choose from a palette of pastel colors to slightly reduce glaring white backgrounds.

Why did my OneNote stay white when I changed my Windows theme to Dark?

OneNote might be manually set to a light theme. To fix this, open OneNote Desktop, click on 'File', select 'Options', and go to the 'General' tab. Look for the 'Office Theme' dropdown menu and change it from 'White' or 'Colorful' to 'Use system setting' or 'Black'.

Are there third-party add-ins to create custom OneNote themes?

While there are powerful macro tools available for OneNote, such as Onetastic, there are currently no safe, verified add-ins that allow you to override the core UI theme colors of the OneNote Desktop application. Advanced programming workarounds should be discussed in the Microsoft Q&A community.

Does OneNote for Windows 10 have different theme settings than OneNote Desktop?

Yes, OneNote for Windows 10 (the UWP app) handles settings slightly differently. In OneNote for Windows 10, you can go to Settings and More (the three dots in the top right) > Settings > Options, and choose Light, Dark, or Use my Windows mode under the Color section.
