1. Using Too Many Colors
When choosing your wedding colors, simplicity is key. Pick three to four colors total to keep your bouquets and centerpieces from looking too messy. If you prefer an undone look, opt for a few slightly varied shades of the same color. This will add depth without looking too chaotic.
2. Choosing Trendy Colors
It’s easy to let the magazines tell you the hottest new color combos.  However, you should think about the colors and patterns they surround yourselves with daily. So look around! Ask yourself what colors make you happy? What color is your favorite room or sweater? Some of the prettiest weddings we’ve seen were inspired by the simplest meaningful objects, like a dress or even a pillow.
3. Choosing an Oversaturated Color Combo
One of the biggest pitfalls in color selection is not considering the eye’s need for rest and calm. The key is balance. If you love bright orange, pick a more muted secondary color like pale blue or khaki. The resulting contrast will let your favorite color take center stage.
4. Choosing Predictable Colors
Certain color combos come with certain connotations. (Think: red, white, and blue or red and green.) Keep your colors from reminding guests of their favorite holiday by subtly tweaking your hues. The trick is choosing a more fashionable shade. Bandana-red, faded denim, and eggshell will banish any Fourth of July memories and forest green and pale pink are anything but Christmas-y.
5. Ignoring Texture
Instead of simply relying on colors, bring multiple textures into your wedding day to give the room some depth and dimension. Mixing textures in the same hue can add more drama and depth to your wedding than simply combining multiple colors. Do this with your flowers, tablecloths, or bridesmaid dresses — varying patterns and surfaces can play a huge role as your wedding palette evolves.
6. Ignoring Your Venue Colors
When deciding on a scheme, consider the reception space or choose a space without decor or color. If you’ve chosen a country club with navy and maroon carpets, a color scheme of lime green and hot pink will clash, and there’s really no way around it.  That’s not to say you have to choose a color that perfectly matches the floors. Use the venue’s decor more as a guide when picking out tones and hues.
7. Limiting Yourself To Two Colors
We’re so over the idea of the strict “color combo.” Many gorgeous weddings feature a variety of colors, sometimes up to five, that work together to create a specific sensibility.
8. Not Coordinating Your Paper Elements
Your invitations set the stage for the event, so let them introduce your wedding colors and evoke the right tone from the start.
9. Trying to Color-Match the Flowers
If your primary wedding color doesn’t come in many flower forms, don’t force it. For example, very few flowers come in blue naturally, and the ones that do are extremely seasonal (like hydrangeas). Instead of insisting your floral bouquets and centerpieces match, ask your florist to choose complementary neutral flowers that will soften (not compete with) the color scheme. Then let your nonfloral elements (like the centerpiece vases and bouquet ribbon wraps) show off your color.
10. Insisting the Bridal Party Wear Your Colors
When it comes to your bridal party, come up with the most flattering color in your palette and use it. In other words, feature your table linen overlays, dinner plates and glassware in the unwearable colors, and let your bridesmaids rock their looks in a flattering color like eggplant, navy, blush, dark brown or black. Not only will they look better — so will your wedding photos!
