Really simple would be rail fence, and you could tone it down with white.
Another idea would be to make a flag with a big block of the blue firework print as the blue field, then cut alternating strips from the red, putting white between. Can you picture that? Basically a red and white jelly roll quilt with a big blue fireworks block in the upper left corner. Or, do a pinwheel using the blue fireworks with white as your "field of stars" in the corner.
