Yes- with us having an outdoor wedding, we want colors that will compliment the scenery, not take away from it, so we decided to have a color palette. For women in attendance, dresses in copper, taupe/dune tones and blush nudes. For men, neutral/pastel earth tone shirts and khaki/tan, gray, or blue/navy pants are acceptable.
