Does the color of the cake have to match the colors of the wedding? My mother keeps telling me that the cake needs to coordinate and even wanted me to match it to the BM dresses. I def don't want to do this now since the dresses are brown. Our other colors are cream, pink, and green, but I want the cake to look like wedgwood china (which I think would look best in blue). Do I need it to match? Will people think it's odd if it doesn't?
