I think peach is the new pink.  It is soft, feminine, and lovely but you can sell your fiance on it because it isn’t pink.  And it works as a neutral because you can pair it with almost any other color and it works.  You can pair it with brighter colors and make your palette cheery and summery like this, or with browns and tans to make it more rustic like this.  But I think my favorite pairing is with another soft color, like this peach and sea glass green combination.

If I were getting married all over again I think this would be my chosen color palette!  It is just.so.pretty!
