Here's a port of the Apprentice theme for Vim to IntelliJ IDEA and other JetBrains products. You can install it by dropping the icls files into .IntelliJIdea*/config/colors and selecting the theme in settings. Some notes:

• This theme works was created with IntelliJ's Darcula theme in mind. A "light" version is available that should work with the default color scheme. This theme isn't actually "light" in the typical sense, however.
• Vim's color schemes for different languages are kind of bonkers. This is no fault of the Apprentice scheme -- it's the way Vim's syntax plugins identify different keywords. However, I've done my best to make languages look consistent in IntelliJ.
• I've taken some extra design liberties in some languages where things just looked better when tweaked. This is largely because IntelliJ and Vim identify cetain language constructs differently. The original color palette has been preserved.

This scheme was developed and tweaked for the following languages and views. Others may work as well.

• Bash
• CSS
• Diff view
• Django/Jinja2 templates
• ERB
• Go
• HTML
• Java
• JavaScript
• Less
• Mako
• Markdown
• PHP
• Perl
• Perl
• Python
• RegExp
• Ruby
• SCSS
• SQL
• Scala
• XML

• Please test changes by closing/reopening IntelliJ and making sure the color scheme "sticks." It's a bit buggy.
• Be sure to run make after modifying Apprentice.icls to generate the "light" (Default/non-Darcula) version.
• When in doubt, don't let attributes "inherit" from another. If your diff includes "baseAttributes", then you should go back and fix that. IntelliJ just doesn't work well enough here.
