Dark Cyan is a cool color that combines the coolness of both blue and green. In addition to the calming attributes of cool blue, dark cyan may also carry some of the symbolism of green such as balance, harmony, and stability. Adding a grassier green (R70G140B0) makes the cyan bluer. The orange is dark, almost brown (R140G44B0) and makes a good neutral color for the blue, green, and purplish red (R116G0B58). In this palette the orange is almost a neutral color and the blues and greens are cool, calming colors. The purplish red injects some warmth, energy, and richness into the cool palette.
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.
