My wedding is 2/16/08 in the evening. I had picked the colors Navy Blue & Silver and was going for a wintery/icy/snowy theme to the wedding. However, I didn't anticipate falling in love with a non-white dress. My dress is called "light gold" which is really an ivory/cream color. So now I'm second guessing the Navy/Silver. What should I use?

You could still do navy and have cream as the accent color. Or a navy and shiny champagne color - almost a gold.
