Imagine the colors you choose for your wedding day. Every bride has a personal favorite color, so incorporate that into your design plan to set the style and tone for your entire event. Look at the colors in your bridesmaids' dresses, cake, favors, flowers, accessories, decorations, table linens and don't forget your invitations! Use a color pallet wheel so add ascents to your color theme.
What mood do you want to create? Vibrant colors add drama, while soft colors evoke a more romantic atmosphere. Use Pastel colors to add a soft eclectic style. Take into account where your wedding will take place. If indoors, look at the wall colors for possible accent up lighting and don't forget the color of the floor, carpet, and draperies. If outdoors take into account the colors of the seasons. Choose colors that complement the setting. Spring and summer colors tend to be lighter, while fall and winter colors are usually darker.
Try to limit your main colors to two or three so as not to look too erratic and stay consistent with your colors throughout the wedding site. Use a few subdued colors for an elegant look.
Choosing the right colors will also allow your photographer and videographer to stay consistent in their color balance. Just remember to allow for some type of lighting so that they can get focus. Especially during the reception, many couples will lower the lights too low and this is a HUGE mistake. So many good shots are ruined due to bad exposure and a very high ISO to get a somewhat decent photo. Good lighting should balance just the right amount of ambiance and your colors.
