My first reaction was ARGH. But it definately has something :)I usually have a hard time with to much colour (use the Twilight theme myself) but perhaps colour is a good idea ... I just have a slight problem with such a hard black background.
So I changed background to #222222, undid the italicized comments (since I use Monaco 9 non-antialiased) and it looks pretty good now. Except that it's still ugly. Ugly but possibly useful.
I just can't stand the looks of things with background or underline, but I realize it can be quite useful.
