Flowers should be complementary. Not just from a color perspective but also when they are placed in the background. It is important to have a similar flowery theme throughout so that your flowers can shine against the backdrop and you can get excellent photographs. For example, if your floral arrangement has pampas grass, then incorporate it in the décor. Consider the colors of your bouquet to be the focal point for everything else in the room.
The color scheme should match what’s in your bridal bouquet as closely as possible. It will give you that “wow” factor that everyone loves about weddings. If you have flowers on either side of the aisle during your ceremony or at an altar, try not to use too many bright colors because they will distract from everything else!
