"When art critics get together they talk about Form and Structure and Meaning. When artists get together they talk about where you can buy cheap turpentine." - Pablo Picasso
Changing the console output color is easy on *nix terminals with escape sequences, but has a funky API on Windows (see the color support code from Testoob for a Python example with pywin32/ctypes).
It turns out that there's a very nice .NET API for it, though (there's a nice article by Sam Allen on the Dot Net Perls site). This would be awesome for Testoob's IronPython support.
