One of the most fun activities for a wedding is choosing colors. There are some great sites to help you out. One is http://www.theperfectpalette.com/. It is a very easy site to use and gives ideas for adding areas of color to your event via food, drink, clothes, and so forth.
You can choose your primary color, and you'll find a myriad of combinations. Here are just two of the selections based on yellow.
For a broader and very different color selection, many outside of the wedding scene, check out http://www.colourlovers.com/palettes and http://www.colourlovers.com/wedding.
