I don't know if you've all seen this, but there is a special issue of Martha Stewart out there that is pretty fantastic. It's a special color issue that helps bride's find the color pallette of their dreams and maybe inspire you to take some chances that aren't as obvious. Color is sometimes hard since a lot of us are afraid of it, or don't do a ton of it in our everyday wardrobes, and I think this issue is a must read for brides starting to tackle the design issue. Color is the basis for the most magical looking weddings- but remember- read with caution- nothing is worse than a color pallette that doesn't "go" with your reception venue or ceremony site.
