A monochromatic color palette can be just as fun and cheery as a multicolored one, and I think this board proves that. The bride who requested this board is working with a navy and shades of blue palette for her September beach wedding in New England. Her theme is elegant, preppy beach with a touch of a rustic feel. I think the grey and navy is a nice alternative to the usual khaki and navy seen at a lot of "preppy" weddings.
