About navy blue

Named for the dark blue-black of 18th-century naval uniforms, chosen because indigo dye was cheap and hid dirt. It is the go-to "serious but not black" background.

The values above are computed from the sRGB hex #000080. The OKLCH form (oklch(27.1% 0.1879 264.05)) is worth noting: unlike HSL, its lightness matches how bright the colour actually looks, which makes building consistent shade scales far easier. To tweak this colour or convert one of your own, open the full colour converter, and check readable text pairings with the contrast figures shown above.

Accessibility note: text needs a contrast ratio of at least 4.5:1 for normal body copy under WCAG AA. Against white this colour scores 16.01:1 and against black 1.31:1 — use whichever clears the bar for the text you place on it.
