If you are going with a colored wedding theme it could be cute if you make your shoes the color of the wedding. It will add a bit of an accent that you wont always be able to see, but will be nice for photos. Also if you plan on using pink as an accent color you can get a simple black and/or white cake with pink accents. As for centerpieces, adding your wedding color into a bouquet of white flowers will be gorgeous. Just a few ideas!
