I read this question and played with a color theme with dark background. It looks cool in Java editor but not for other editors. Then I tried to use the default color themes by clicking "Restore Defaults" buttons for ALL editors in Preference dialog and refering to this question. But in the file compare view the background is still black and the differences between compared files are hardly to discern.
Any way I can restore the backgound color in file compare view?
just remove a few lines which are about color in:
{workspace}/.metadata/.plugins/org.eclipse.core.runtime/.settings/org.eclipse.ui.editors.prefs
then restart your eclipse, that's it.
