Navy blue carries the blue symbolism of importance, confidence, power, authority, intelligence, stability, unity, and conservatism. To keep the color scheme from being too conservative add some energy and warmth with a pinky-red (R183G0B149) and an orange-red (R255G64B0) and that mellow yellow (R255G217B0). Although green is a cool color like blue, green with blue produces echoes of nature - water and forest and can denote new beginnings and growth.
The orange, yellow, green also lend the palette a fresh, citrusy flavor.
You don't have to use these exact shades. Go a touch lighter or darker, or step one spot to the left or the right on the color wheel. These color combinations are just to help you find a suitable color palette using dark blue as the main component.
