While you make a good point, the color scheme is actually one of the most important parts of a wiki. It impacts how people will see the page (quite literally) from then on, and it usually shouldn't be changed even if the background image does. Even the background image shouldn't be frequently at all, which is why considering both is important. A certain image might not be suitable because the page colors would need to change drastically, for example.
