There are no color restrictions in winter, though its palettes lean more toward deep greens, reds, mauves, and aubergine, accented with bright winter whites and a touch of pink or blue. Take into account the colors you are considering for the other elements of your wedding -- the bridal party ensembles, the table linens, even the cake. Also, consider nature's other winter wonders such as bright white snow or dark green holiday wreaths.
