Automatic detection of background colours & vector definitions

Whenever you choose a custom background/wall it looks awful if you don't change your walls texture, too: they don't (visually) match!
Adding automatic detection of desktop colours would be nice: if I have a sky photo then my walls will be blue; a dark minimalist background would make them black and so on...without having to create wall textures manually. I think that could be done detecting edge colors (to maximize the blending between walls and floor) or average colors (the dominant colors in all of the image).

One more thing, adding "vector" colors might be an idea: choose a color instead of an image for your textures, or define a gradient!

What about it? Easy to implement, great to have ;) Hope you like it too!
