No bridal party how do i show off my colors

You can show off your colors through your decor, your flowers, your accessories, your cake, your centerpieces, etc. The options are endless! At your reception, you could have dark green or burgundy tablecloths with sunflowers as centerpieces. You could include sunflowers on the design of your cake and/or in your bouquet. You could put burgundy and yellow into the design of your invitations, vow books, and/or guest book. Your fiance could incorporate dark green into his attire. You could incorporate green, burgundy, and/or sunflowers into your accessories (hair clip/headband, veil, jewelry, etc). The altar could be decorated with your colors. Here are some inspiration photos I found on Pinterest:
