Ruby Blue is a collection of themes for different text editors that mimic the colors used in the code samples on the website for the Ruby programming language (http://ruby-lang.org).>
Unfortunately, the Ruby Sugar doesn't quite allow the degree of formatting that the PHP Sugar does, so ironically Ruby files look pretty nasty under this theme -- nothing like they look in TextMate. PHP, CSS and HTML files, however, a nearly identical to their TextMate counterparts. Tip: Use Bitstream Vera Sans Mono - Roman, 11pt for the nearest-to-TextMate look, because Espresso Mono doesn't presently support italics.
