The Wikia's colour scheme

I'm perfectly fine with the current colour scheme, however I feel a lighter one would be a bit more appropriate (note: I don't know if Wikia enforces only predefined styles or allows for customisations) to reflect the show's general design practices (light with darkish colours for artistic effect).

Also, the current background image is of fairly low quality, so if we could at least change that.

Maybe, if enough people agree, we can submit a few designs and vote for the most appealing one?
