The results are in from our survey, asking our readers what their primary wedding color will be. Purple and blue were the most popular, followed closely by red and green. We love the elegant shade of dark eggplant purple, the cool blue hues of vibrant turquoise, muted denim and gray-blue frost, rich scarlet red and earthy greens, including basil and pale meadow for this season’s weddings and events.
A general guideline for how to use colors throughout your wedding is to select one primary (60%), a secondary (30%) and an accent (10%). Your wedding reception location is a good place to start when choosing a primary color, make sure the venue decor fits in with your scheme. I like using a neutral for the secondary and a bright or contrasting color as the accent. Use your primary color for your wedding invitations, bridesmaid dresses and table linens. The secondary could be used for centerpieces, flowers, cake and favors, then sprinkle in a splash of the accent color with your embellishments.
