Menu Display
I'm thinking that in future versions of MuseScore, there should be an option that allows users to use a dark mode interface and the measures as well as notes and text should be white instead of the usual black on light interface, which is normally traditional for musicians

I believe this is already implemented for the MuseScore 4, to be released sometime within the next few months or so. Meanwhile, most OS's provide such a mode that affects all apps, often in the "accessibility" options, so you can probably have this result already.
