Fix OneNote iPad Ink Appearing White on Windows or Web
Question details
Handwritten notes created with black ink on an iPad appear as white or invisible when accessed via OneNote for Windows or the web interface.

- Product
- Microsoft OneNote
- Device & OS
- iPad, Windows
- Scenario
- Viewing and syncing handwritten iPad notes across different platforms and devices.
- Observed behavior
- Black handwritten ink turns white or entirely invisible on screens with a light background when synced from the iPad to a Windows computer or the web.
Ensure your iPad is connected to a stable internet network so that any synchronization tests accurately reflect your changes. Also, confirm that your OneNote app is fully updated to the latest version on both devices.
Disable Dark Mode and Color Inversion on iPad
Adjusting the display settings on your iPad prevents color inversion, ensuring your black ink registers correctly before syncing to Windows or the web.
OneNote automatically adapts pen colors when switching between dark and light modes. If dark mode or accessibility color inversion is active on your iPad, you might inadvertently use white ink on a dark canvas, which then remains white when synced to a light canvas on Windows.
Open the Settings app on your iPad, tap on 'Display & Brightness', and select 'Light' to temporarily disable dark mode.
Go back to the main Settings menu, tap 'Accessibility', then select 'Display & Text Size'. Ensure that both 'Smart Invert' and 'Classic Invert' are toggled off.
Open the OneNote app, create a brand-new page, and write something using the black pen tool. Force a sync by swiping down or checking your sync status.
Open OneNote on your Windows PC or the web browser, let the notebook sync, and check if the newly created handwritten ink appears in black as intended.

Frequently Asked Questions
Why does my pen color change automatically in OneNote?
OneNote sometimes adapts ink colors automatically when you switch between light and dark modes to maintain text contrast. If a black pen is used in light mode, it might flip to white in dark mode, or vice versa, causing visibility issues during cross-platform syncing.
Does Smart Invert on iPad affect OneNote syncing?
Yes, if Smart Invert is active on your iPad, you might unknowingly select white ink thinking it is black because the screen colors are reversed. When that note syncs to a PC without color inversion, the actual white ink is displayed on a white background, making it invisible.
Can I fix the invisible ink directly from my iPad?
Yes, but you must first ensure your iPad is set to Light Mode. Once in Light Mode, use the lasso tool to select the white ink, then change the pen color back to black in the toolbar.
