FI is wearing a tux (his choice), but I agreed to A.F. Blue as a primay color.  My first insticnt was silver for accents (inc. shoes maybe a sash....at least on the "role-to-be-determined 10yo girls).  Then we moved it to April and I though yellow might be brighter, springy-er and good for flowers.  
Thoughts???  Do all three "work:"?  Where woud I pop-in the secondary colors? I am SO not a girl's girl and need help onf such things.
