I prefer dark backgrounds for coding, and I\'ve downloaded a jar file containing an IntelliJ IDEA color theme that has a dark background. How do I tell IntelliJ about it?
Like nearly everyone else said, go to file -> Import Settings.
But if you don't see the "Import Settings" option under the file menu, you need to disable 2 plugins : IDE Settings Sync and Settings Repository
Go to File->Import Settings... and select the jar settings file
Update as of IntelliJ 2020:
Go to File -> Manage IDE Settings -> Import Settings...
Find the .jar theme file in your disk. Drag the file into PhpStorm window and voila !
Interesting I never spent too much time adjusting the colours in IntelliJ although tried once.
See link below with an already defined colour scheme you can import.
Where can I download IntelliJ IDEA 10 Color Schemes?

Download the jar file, file import the jar where you will see a what to import ;)
Take a look here: Third Party Add-ons
You may have to extract the jar using a zip application. Hopefully inside you'll find a collection of XML files.
