How to Make PHPStorm / Intellij IDEA Dark (Whole IDE, not just color scheme)
Solution 1:
Settings (Preferences on Mac) | Appearance | Theme = Darcula
P.S. Since IntelliJ IDEA v14 / WebStorm v9 / PhpStorm v8.0.2 (and any other IDEs on branch 139.xxx or newer) the settings path is a bit different:
Settings (Preferences on Mac) | Appearance & Behaviour | Appearance | Theme = Darcula
Solution 2:
View -> Quick Switch Theme -> Switch Look And Feel -> Darcula
and Restart the IDEA
if changes do not become apparent.
Solution 3:
Download and enable ColorIDE.
Preferences > Plugins > "Browse repositories..." button > search for "ColorIde"
Instead of being limited to the standard 4 themes that come with the IDE, ColorIDE plugin will give your IDE the same look and feel as your current color scheme.
