I have been trying to change the background color of Eclipse\'s windows to black and customize the font colors. There doesn\'t seem to be a way to do this, at least not in a
Background color of views (navigator, console, tasks etc) is set according to the desktop (system) settings. On Linux/GNome I changed System/Preferences/Appeareance to change this color.
Editor colors are set chaotically by different editors, search for background in eclipse preferences to find different options. One easy way to get beautiful dark (and not only dark) themes is to install Afae plugin, and then pick theme within its preferences (twilight theme is beautiful, for example) - again, eclipse prefs, Afae group. Of course this applies only when you edit with Afae.
If you are having trouble with Eclipse 2019 and using a dark theme and setting the background and having it not change: There seems to be a recent Eclipse bug. I suggest you look here or here for workarounds.
You can install eclipse theme plugin then select default. Please visit here: http://eclipsecolorthemes.org/?view=plugin
If you go to Windows, Preferences then select General, Editors, Text editors, you can set colors on that property page (and there's a link for setting MORE colors - General, Appearance, Colors and fonts).
That's with an Eclipse 3.3 build anyway.
