I want to start this by saying that I am NOT interested in changing the Microsoft Word theme to only one of the default themes (Black, White, Colorful, or Dark Grey). I am instead interested in being able to customize and change the look and appearance of my Microsoft Word with much more control in order to actually personalize it.
For example, I like the color scheme of the dark grey theme the most, however, i cannot stand having a solid white page background, as it's too harsh on the eyes. However, Microsoft's Black theme is not only far to high-contrast for my liking, but is somehow equally harsh on the eyes and harder to read. As such, i would like the option to actually be able to customize the appearance to fit what works best for me, personally, as opposed to Microsoft's terrible selection of color pallets. Even if i have to install a plugin on add-in, since I figure this likely isn't possible without something like regedit or modifying the program's code directly.
I'm about at the end of my rope with this thing, i have severe eye strain, and if I can't change the color theme to actually be something decent, I'll have to drop the Microsoft Office suite of products and get something that i can actually use without straining my eyes. Changing the basic color and appearance of a program should honestly be a default feature, especially when it's already an option, but just limited to 4 terrible colorways.
