Tim, this subject has been discussed over and over again, as explained in this past post:

Fortunately a solution is finally coming up to please the majority of the users.
As explained in the article above, the users will be allowed to create new presentation design themes for the site that will allow them to define aspects like colors, fonts, and certain aspects of the layout.
Then there will be a contest to pick the most appreciated design theme. besides the usual fame, the winner win gain a free life time premium subscription, a big elephpant PHP mascot plush toy and a symbolic money to pay for the rights of use the artwork in the site.
Although this has been planned for a while now, despite it is not ready, the design editor project will only be announced next week, because other projects with priority had precedence like the job board.
For now, stay tuned to the announcement in the site blog.
