I love the idea of using metallics for fall weddings - and rich elegant colors like this dark plum, paired with gold, makes a beautiful fresh fall color scheme. The colors remind me of champagne and wine grapes - and that makes them a great harvest choice. I especially like the use of a print table cloth in the top photo and the gold detailing on the side table - little details like that can really take a decor scheme from OK to Outstanding.

You could very easily work grapes/grape vines into this color scheme for a perfect, harvest vineyard feel! For a more modern touch, choose a darker shade of purple then the one shown here.
