Colour Theme

Hi
I desperately need someones help. Iam getting married next year in August but cant decide on a colour theme.
Both me and my fiancee love blue but we want to match it to something else. My sister suggested chocolate brown only problem is I havent seen any pics of those colours used together.
Can someone please help send me a few pics to help me make up my mind or even give suggestions on how to follow the theme throughout???
