If you want the text area specifically to be pitch black with vibrant syntax highlighting, you should use the . Deep Black: The most popular "true black" theme.

Customize (like making comments easier to read).

Which do you use most often in Notepad++? I can recommend a theme that handles its syntax best.

In recent versions (v8.0 and higher), Notepad++ introduced a native Dark Mode that skins the entire application, including the toolbars and menus. Open . Click on Settings in the top menu. Select Preferences . Choose Dark Mode from the left-hand list. Check the box for Enable dark mode .

Visit sites like GitHub or the official Notepad++ Community forum to find .xml theme files.
