Keep note sheet as black text on white background while Notes.app is in dark mode I am enjoying dark mode in macOS Mojave. This includes the list boxes and sidebar in the Notes.app. Except, the note sheet itself is awkward with white-text-on-black-blackground. 

Is it possible to keep most of dark mode except the content of each note?
Yes, user preference

Yes, indeed, you can display your note sheets in Notes as black-ink-on-white.

Go to Preferences dialog box. While I did not notice it immediately, you can find a checkbox under the text-size slider. That checkbox is titled Use dark backgrounds for note content. Uncheck that box.
