In addition to being used in the centerpieces, food can be an extension of the color palette--steamed shrimp and carrots, blood orange cocktails, etc.
Circles are sort of a secondary theme of this wedding, from the shape of the daisies and orange slices to the dots on the cake, and the paper lanterns hung from the ceiling to the round tables.
The wedding has clean lines and a bit of a retro feel--just my friend's style.
