It has been a while, but in case you are still interested, there is a new plugin for console colorizing: Grep Console.
Works nicely with Intellij 12.
Make sure you restart IntelliJ after installing the plugin. After you will see the plugin icon in the top left corner (white-red icon).
Works like a charm. Thanks a lot for sharing :)
A recent version of the config file for GrepConsole is available in my dotfiles. You can copy or symlink it to
$HOME/.IdeaIC12/config/options/GrepConsole.xml.@JJD cool, thanks. And thanks for turning a valid answer into a good one :)
Works in IntelliJ 13 EAP as well. Thank you.
Support for ANSI coloring in the Grep Console plugin was removed in version 6.4 (feb 2017, IJ 2016+).
