Sophie's Favor's webstore carries not only aqua blue favor boxes, but also aqua blue ribbons, gift tags and labels. I was amazed at how many different colors work well with aqua blue as shown on their website -- black, red, other blues, purple, brown, pink, white, ivory or champagne, gold, and even dark green. My personal favorite would have to be red or pink with aqua blue. There's something about combining cool colors with warm colors that makes for such a striking, impressive palette.
Much Aqua Blue Love,
