That colour scheme is not as bad as the one on cpanforum.com: blue on
grey, with red and yellow highlights??? Aaargh! Another dreadful design
is the one on perlmonks.org, whose colours come out fairly normal but
which guarantees to make every single font the wrong size.
A useful trick for browsing the WWW, if you have Firefox, is
View -> Page Style -> No Style
It works on removing Larry Wall's hideous colour scheme, and on cpanforum.com, but it doesn't help much with perlmonks.org.
