IntelliJ IDEA Enable Color Management Plug-in
The issue is reported as IDEA-149601, when you're using IntelliJ on OS X, all colors used in the windows are rendered more contrasty.
This is not happening on Apple's JDK 1.6.
Use Gradle to build this plug-in. Required OS X and Xcode or Xcode command line tools since this plug-in includes a native extension.
