Hi
Bluetoblitz,
Thank you for posting here in the Microsoft Community Forum.
We got your concern about the way on how to change the background color of a text box in OneNote. We’ll check on this accordingly and see how we can sort this out.
This would be depending on the OneNote platform being used, as options may vary. To know more about the situation and to help us replicate this concern, so we’ll know if the functionality is available or not, we’d like to make sure with the OneNote version
that you’re using, is it the OneNote 2016 included in your Office suite or the
OneNote for Windows 10? Please see the image below for its difference:
Are you referring to the actual box/container that holds the text on a page of a notebook? Or is highlighting the texts to your preferred color? Would you be able to provide a
screenshot of this, so we can verify the exact view of what you’re trying to accomplish?
We’ll wait for your response.
