Color Scheme Ideas Needed :.)

Hi everybody,
I´m getting married in April of 2003 and I work for a hotel. I´m getting a great deal with the banquet hall but I´m worried about the colors. I don´t want to clash and make everything look tacky. The walls of the hall are a pastel yellow, the chairs which are beautiful are blue green with gold trim and the carpet has a ton of colors: terracotta, light yellow, light green, hunter green, blue green and champagne. Does anyone have any ideas regarding possible color schemes?? I could alawys use chair covers!! Please let me know..... Your help is deeply appreciated! :.)
