One of the earliest steps of the wedding planning process is choosing your wedding colors, but if you simply can't narrow it down to just two or three, then a rainbow wedding theme might be exactly what you need. We'd recommend this color-filled wedding theme to anyone who wants to create a whimsical, happy atmosphere on their special day (and for anyone who thinks more is more, because that's what this whole aesthetic is all about). Not only is a rainbow wedding theme the best way to ensure that your big day is filled with colorful details, it's also a meaningful—and popular—way for some LGBTQ+ couples to celebrate your pride and the start of a new life together. Check out some of our favorite rainbow wedding ideas right here.
