Chocolate Brown And Baby Blue

Hi I`m getting married next Valentines day 2008, and my them was The Chocolate brown and Tiff blue but my fiance didnt like the tiff blue he prefers sky blue so I`m having problems deciding on the decorations and center pieces. I was kind of thinking of the hearts decorations for valentines. I`m not sure of what colors to go with for the groomsmen, I saw this real pretty dress that is white and it has a light blue band right below the breast. So I`m not sure of what my fiance s going to wear and how to do the centerpieces. The light decor is a good idea. Please someone give me advice?
