Are you wanting to do a consistent color theme? Is it color that tripping you up or page design? If it's page design, check out pagemaps.com. There are lots of page design ideas! Also, consider doing some "challenges" here on sb.com. I'd also suggest checking out the gallery and tag pages you like so you can scrap lift them. Good luck!
You can also search the gallery here by color. Pick the main color you want for a particular page and maybe go to the gallery and search by that color. If you go under the layouts tab of the gallery, you'll see a tab below it for colors. Good luck!
