They will certainly work together. There are a number of patterns that work well for 2-color quilts, or add others, such as the black/white suggested. If you don't want a completely 2 color/fabric quilt, you might consider a mild tone of one, such as a medium-light blue for sashing. My personal preference would be oversized, high-impact blocks, such as 16" sawtooth stars or 18" friendship stars, with the orange on the navy. Pinwheels can be made just about any size and can have a "pow" effect with a sashing.
