One notch above navy: Dark Blue

Within the X11 palette, Dark Blue sits one visible step above navy: #00008B pushes the blue channel slightly higher than navy's #000080, and on a well-calibrated screen you can just about perceive the difference. This is blue at maximum concentration — no red, no green, nothing but the primary itself.

That purity makes it a strong OLED-adjacent wallpaper: nearly as battery-friendly and dramatic as black, but with unmistakable character. It also excels in slide decks and dashboards as a background that lets white type, gold accents, and data visualizations carry all the brightness. Reserve it for contexts where formality is welcome.

Gold against Dark Blue is the oldest trick in heraldry and still works; white smoke and sky blue lighten the scheme in careful steps.
