I'm aware of this topic: I've used it to change most of the editor colors, and that's great.
But that wasn't enought, there's still too much white (and I need to change it because it hurts my eyes).
I've searched in the preferences (both using Eclipse itself and editing the files) for instances of while (255,255,255) and changed them all. Looks like I'm missing something.
1/ too much white in the UI:
2/ totally white in this screen:
3/ I'm going to cry now
this blue, god, my eyes!!!
Each time you see white or gray color, this is more than likely related to OS system colors.
In other word, to truly have an Eclipse full dark theme, you need first to have a dark theme for your OS, and then your Eclipse will follow.
Here is an example on a Windows7, modifying just one parameter:
Probably not the answer your looking for, however the Intellij community edition is an excellent free IDE, and very easy to use. The background colours can be set and changed to many colours, but also there are a number of free plugins which can customise backgrounds, and the look and feel. Well worth a look if you don't find exactly what your looking for with Eclipse
I see you're on the Mac - the easiest thing to do would go to System Preferences -> Accessibility -> Seeing -> Display -> "White on Black". It will invert everything on your screen though, I don't know, if you'd like that?
