Pink and Yellow
Pink is many a girl's favorite color, but sometimes we arch an eyebrow at yellow. Why? A lot of women don't have the proper skin tone to pull off a yellow dress. That's where pink comes to the rescue. Outfit your bridesmaids in pale pink, and use yellow as the perfect accent color.
Pink and yellow can be a great combination at the dinner table as well. If you're renting china, see if you can do pink and yellow place settings. Also try using colored linens -- no one says the tablecloths and napkins have to be white.
Think about using the colors independently, like pink flowers on the place card table and yellow ribbons adorning the bar. They'll still complement each other.
