I'm using Ubuntu 16.04 and latest Eclipse Neon. When I hover some code, I got my tooltip background black and my text orange. I found it here I must change colors at OS level. Here I saw how to edit colors at OS level. However it didn't work. Even changing Ubuntu Theme, changing tooltip color on Eclipse. I'm using Ambiance right now.


(Duplicate of https://stackoverflow.com/posts/40360725/)

I have verified that

export SWT_GTK3=0

is a viable, albeit suboptimal, workaround in Ubuntu 16.10 and Eclipse 4.6.1 when the desktop appearance uses the BlueMenta themes, with no additional tweaks required.

Tweaking the gtk-3.0 css files didn't work for me.

Other users have had better luck with the scripts in this project


Very late answer, but after some annoying trials (mostly for older Eclipses with GTK2) a simple solution for brand new eclipse 2019-06 and perhaps for other eclipse versions using GTK3:

  1. Install the color-themes-plugin via

    Help>Install New Software

    Add: http://eclipse-color-theme.github.com/update

  2. use the plugin via

    Window>Preferences>General>Appearance>Color Theme

    choose any other then default-color-theme, apply and close Dialog

  3. If you still want to use Default-Theme: reopen Dialog and switch back to default
