How about looking at your pages from another direction then? How about starting with a colour combination...
The Color Room (http://thecolorroom.ning.com) is a great website to look at for inspiration in this area. Not only does it provide inspiration for colour combinations, but it gives you a sketch and ideas for texture on your page. If you still feel stuck, they have guest designers and many interpretations on the sketch and colour choices too.
And if that isn't enough - if you go to the Palettes menu and select Palette Album from the drop menu, you can see all of the previous colour and sketch inspirations.
