The (now old, but still superior IMO) GitHub color-scheme for IntelliJ IDEA. You can see a screenshot here. (But you don't really need to, because it's just like GitHub. Only in IntelliJ.)
The following languages are currently supported with GitHub matching colors:
- CSS
- HTML
- Java
- JavaScript
- Scala
- XML
Please feel free to fork and send pull requests with additional languages or fixes!
Download settings.jar and in IntelliJ go to File | Import Settings... and choose the downloaded jar.
Download GitHub.icls and copy it into the colors/ directory in the IntelliJ preferences folder. In OS X: ~/Library/Preferences/IntelliJIdea12/colors/.
After installation of the color scheme restart IntelliJ and then select the new scheme by going to Preferences | Editor | Colors & Fonts.
