Dear Themis,
Greetings! Thank you for posting in Microsoft Community. We are happy to help you.
Per your description, may I know if your students are using Dark Mode to view the shared notebook?
If not, you may suggest them turn on Dark Mode with steps below.
1.If they are using OneNote on iPhone or iPad:
open Settings on iPhone/iPad > Display & Brightness > select Dark.
2.If they are using OneNote on Windows computer:
a. OneNote 2016:
Open OneNote, go to File>Account>Office Theme, choose Black.
b. OneNote for Windows 10:
In the upper right corner of the app window, click the Settings and More (the 3 dots) button, click Settings, and then click Options.
In the Options pane that opens, under Color, select Dark to use OneNote in Dark Mode.
However, if they are using Dark Mode but still have issue, please feel free to post back and let me know. Please share some screenshots about the issue's symptom. I will continue helping you.
Thanks for your time and cooperation!
Hope you have a nice day, stay safe and healthy always.
Sincerely,
Tina | Microsoft Community Moderator
